Assertions are only supported in the 2.0 stream of jdtcore. Configurable options are also subject to improvements.

4,077 | Bug 4077 JDK1.4 - Assertions - text coloring should deal with 'assert' (1GHS3A3) | If the JavaCore option related to source mode is set in 1.4 mode, then 'assert' is a keyword which has to be coloured properly. Assertions are only supported in the 2.0 stream of jdtcore. Configurable options are also subject to improvements.

4,155 | Bug 4155 Source Attachment wizard for variable classpath entries not correct (1GJ6X9P) | (1) Create a directory containing a .jar file and a .zip source archive for the jar The .zip archive should have a non-null root path to the source. (2) create a classpath variable which points to this directory (3) place this .jar file in your classpath using the variable (4) use the Java Source Attachment wizard to set the source archive Attempt to use the "root variable path". The "browse..." button is inactive unless the text field is non-empty. If the text field is non-empty, pressing the browse... button shows the source archive no matter what is in the field. If you make a selection in the paths shown that are relative to the archive, any path that is deeper than the first is entered without the intervening path variables. For example, suppose the archive resolves to c:\blort\blort.zip. I can type "junk" in the root variable path field to activate the "browse..." button. Pressing "browse..." shows the structure of "c:\blort\blort.zip". If I select work/src/main as the source root directory in blort.zip for blort.jar and press OK the text field for "root variable path" now reads: junk/main.

3,622 | Bug 3622 New Package Wizard has confusing message (1GD0L9O) | 1. Create a new Java Project 2. Select the project. 3. Invoke New Java Package. Result: Before you type anything the following message appears at the top: "A folder corresponding to the package name already exists". At this point my package name field is empty. What does this message mean? Is this an error? If so, should it be displayed in red with the error icon? NOTES: EG (5/1/2001 5:53:41 AM) there should be no error message when the package name field is empty and finish should be disabled. MA (5/2/01 9:34:00 AM) It is a warning. I will remove the message EG (5/2/01 9:43:44 AM) issue how to create a default package? It can't be created by the user since it always there. | verified fixed | 0870c24 | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-22T11:05:19Z" | "2001-10-11T03:13:20Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/NewPackageCreationWizardPage.java | /*

6,207 | Bug 6207 Java project properties dialog grows taller than screen | build 20011116 The Java Build Path/Order page in the project properties dialog always grows the table to show all items. In a workspace with many source folders the properties dialog grows so tall that you can no longer see the ok/cancel buttons. I noticed this while using WSDD (Eclipse 1.0 based) to create P3ML bundles. P3ML consists of about 20 bundles with each bundle living in a separate source folder. Note that the resize only happens when the dialog is reopened. If you create source folders in the properties dialog and then switch to the order page you will see scroll bars. Also, it seems that this only happens when there is a large number of source folders. When I reference a lot of projects the height of the order page is limited and the table shows scroll bars. | resolved fixed | 1b69a90 | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-23T15:07:47Z" | "2001-11-21T22:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/ImportOrganizeInputDialog.java | /*

6,207 | Bug 6207 Java project properties dialog grows taller than screen | build 20011116 The Java Build Path/Order page in the project properties dialog always grows the table to show all items. In a workspace with many source folders the properties dialog grows so tall that you can no longer see the ok/cancel buttons. I noticed this while using WSDD (Eclipse 1.0 based) to create P3ML bundles. P3ML consists of about 20 bundles with each bundle living in a separate source folder.

6,207 | Bug 6207 Java project properties dialog grows taller than screen | build 20011116 The Java Build Path/Order page in the project properties dialog always grows the table to show all items. In a workspace with many source folders the properties dialog grows so tall that you can no longer see the ok/cancel buttons. I noticed this while using WSDD (Eclipse 1.0 based) to create P3ML bundles. P3ML consists of about 20 bundles with each bundle living in a separate source folder. Note that the resize only happens when the dialog is reopened. If you create source folders in the properties dialog and then switch to the order page you will see scroll bars. Also, it seems that this only happens when there is a large number of source folders. When I reference a lot of projects the height of the order page is limited and the table shows scroll bars. | resolved fixed | 1b69a90 | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-23T15:07:47Z" | "2001-11-21T22:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/TypePage.java | /*

6,207 | Bug 6207 Java project properties dialog grows taller than screen | build 20011116 The Java Build Path/Order page in the project properties dialog always grows the table to show all items. In a workspace with many source folders the properties dialog grows so tall that you can no longer see the ok/cancel buttons. I noticed this while using WSDD (Eclipse 1.0 based) to create P3ML bundles. P3ML consists of about 20 bundles with each bundle living in a separate source folder. Note that the resize only happens when the dialog is reopened. If you create source folders in the properties dialog and then switch to the order page you will see scroll bars. Also, it seems that this only happens when there is a large number of source folders. When I reference a lot of projects the height of the order page is limited and the table shows scroll bars. | resolved fixed | 1b69a90 | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-23T15:07:47Z" | "2001-11-21T22:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/buildpaths/BuildPathsBlock.java | /*

6,207 | Bug 6207 Java project properties dialog grows taller than screen | build 20011116 The Java Build Path/Order page in the project properties dialog always grows the table to show all items. In a workspace with many source folders the properties dialog grows so tall that you can no longer see the ok/cancel buttons. I noticed this while using WSDD (Eclipse 1.0 based) to create P3ML bundles. P3ML consists of about 20 bundles with each bundle living in a separate source folder. Note that the resize only happens when the dialog is reopened. If you create source folders in the properties dialog and then switch to the order page you will see scroll bars. Also, it seems that this only happens when there is a large number of source folders. When I reference a lot of projects the height of the order page is limited and the table shows scroll bars. | resolved fixed | 1b69a90 | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-23T15:07:47Z" | "2001-11-21T22:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/buildpaths/LibrariesWorkbookPage.java | /*

6,207 | Bug 6207 Java project properties dialog grows taller than screen | build 20011116 The Java Build Path/Order page in the project properties dialog always grows the table to show all items. In a workspace with many source folders the properties dialog grows so tall that you can no longer see the ok/cancel buttons. I noticed this while using WSDD (Eclipse 1.0 based) to create P3ML bundles. P3ML consists of about 20 bundles with each bundle living in a separate source folder. Note that the resize only happens when the dialog is reopened. If you create source folders in the properties dialog and then switch to the order page you will see scroll bars. Also, it seems that this only happens when there is a large number of source folders. When I reference a lot of projects the height of the order page is limited and the table shows scroll bars. | resolved fixed | 1b69a90 | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-23T15:07:47Z" | "2001-11-21T22:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/buildpaths/VariableCreationDialog.java | /*

6,207 | Bug 6207 Java project properties dialog grows taller than screen | build 20011116 The Java Build Path/Order page in the project properties dialog always grows the table to show all items. In a workspace with many source folders the properties dialog grows so tall that you can no longer see the ok/cancel buttons. I noticed this while using WSDD (Eclipse 1.0 based) to create P3ML bundles. P3ML consists of about 20 bundles with each bundle living in a separate source folder. Note that the resize only happens when the dialog is reopened. If you create source folders in the properties dialog and then switch to the order page you will see scroll bars. Also, it seems that this only happens when there is a large number of source folders. When I reference a lot of projects the height of the order page is limited and the table shows scroll bars. | resolved fixed | 1b69a90 | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-23T15:07:47Z" | "2001-11-21T22:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/dialogfields/CheckedListDialogField.java | /*

6,196 | Bug 6196 Last item selected by default in variable selection dialog | Build 20011120 - go to add a classpath variable - Browse for var name - it selects the last item by default Normally the default selection is the first item. This seems picky, but it's actually fairly annoying when using keyboard navigation for the default selection to be in the wrong place. (particularly when the one I always go for is ECLIPSE_HOME, which is always the first item <g>). | verified fixed | e26dfad | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-23T15:53:36Z" | "2001-11-21T22:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/buildpaths/BuildPathsBlock.java | /*

There is java.lang.ClassCastException at org.eclipse.jdt.internal.ui.javaeditor.RunToLineAction.getContextFromModel (RunToLineAction.java:111) The getContextFromModel() method incorrectly assumes that all debug targets are of type JDIDebugTarget.

4,974 | Bug 4974 Set classpath / output location should be one operation | 204: 1. create a project with 'src' as source folder and 'bin' as output location. 2. in the project properties change the setting to use the project as source folder and the project as output location. Press Ok You get the error message: 'Cannot nest outputfolder /xy in source folder /xy/src' The problem is that setting outputlocation and classpath are two operations. By setting the first, an illegal state is created. -> Like the validation (checking classpath and outputlocation at once), the setting of classpath / output location should be offered as one operation. Note that the error message is strange. I guess it should say: '/xy/src' can not be nested in '/xy' | resolved fixed | 35d95cb | JDT | https://github.com/eclipse-jdt/eclipse.jdt.ui | eclipse-jdt/eclipse.jdt.ui | java | null | null | null | "2001-11-30T15:01:58Z" | "2001-10-15T10:00:00Z" | org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/wizards/buildpaths/BuildPathsBlock.java | /*

DB (31.07.2001 15:12:06) The current change infrastructure doesn't support any kind of overlapping manipulation. So this is somehow by design. What you can do is to create two distinct text changes.

DB (08.08.2001 14:50:58) I opt to not fix this PR since creating two document changes fixes the problem, although it is not optimal from a speed point of view (the document gets read two times).

4,052 | Bug 4052 document change infrastructure - missing functionality (1GH2DWC) | AK (7/18/2001 4:45:27 PM) i stumbled across this when doing Reorder Parameters. consider the following text: m(m(1, 2),3) lets's say you want to swap the parameters. so your desired output is: m(3, m(2, 1)) you create 4 move entries in the change creator (first 'm' has position 1): . move(5, 1] -> 7 //moves the first parameter of the inner call . move[7, 1] -> 5 //moves the 2nd parameter of the inner call . move [3, 6] -> 10 //moves the first parameter of the outer call . move [10, 1] -> 3 //moves the 2nd parameter of the outer call this gets splitted into 4 replaces (will not give details here - see code of AbstractTextBufferChange) anyways, the replaces are sorted backwards before execution. to cut the story short - you end up with: m(3, m(1, 2)) the reason is: the moves are treated in the same way as replaces. they should not be, if they overlap. there should a hierarchy of moves - or another way to say: 'this move must be done before that move' in the case above - the inner moves must be done before the outer ones. this is quite serious and i'm not sure how to nicely work around it. DB (31.07.2001 15:12:06) The current change infrastructure doesn't support any kind of overlapping manipulation. So this is somehow by design. What you can do is to create two distinct text changes. The first changing m(1,2) to m(2,1) and a second one changing m(m(2,1), 3) to m(3, m(2,1)).
