Bug 149800 [JUnit] NPE while copying editor code to clipboard during JUnit run
Reported: 2006-07-06 06:19:34 | Status: verified fixed

Build 3.2.0 While JUnit tests were running, I selected some text in a Java editor, and performed a copy action. A dialog popped up saying a NPE had occurred, see trace below (from console). It seems that there got some confusion in dispatch in between the editor thread and the Junit run. !ENTRY org.eclipse.ui 4 0 2006-07-06 12:20:01.989 !MESSAGE java.lang.NullPointerException !STACK 0 java.lang.NullPointerException at java.io.StringReader.<init>(StringReader.java:33) at org.eclipse.jdt.internal.junit.ui.JUnitCopyAction.convertLineTerminators(JUnitCopyAction.java:90) at org.eclipse.jdt.internal.junit.ui.JUnitCopyAction.run(JUnitCopyAction.java:64) at org.eclipse.ui.actions.BaseSelectionListenerAction.runWithEvent(BaseSelectionListenerAction.java:168) at org.eclipse.ui.actions.RetargetAction.runWithEvent(RetargetAction.java:229) at org.eclipse.jface.commands.ActionHandler.execute(ActionHandler.java:119) at org.eclipse.core.commands.Command.executeWithChecks(Command.java:461) at org.eclipse.core.commands.ParameterizedCommand.executeWithChecks(ParameterizedCommand.java:424) at org.eclipse.ui.internal.handlers.HandlerService.executeCommand(HandlerService.java:160) at org.eclipse.ui.internal.keys.WorkbenchKeyboard.executeCommand(WorkbenchKeyboard.java:466) at org.eclipse.ui.internal.keys.WorkbenchKeyboard.press(WorkbenchKeyboard.java:799) at org.eclipse.ui.internal.keys.WorkbenchKeyboard.processKeyEvent(WorkbenchKeyboard.java:846) at org.eclipse.ui.internal.keys.WorkbenchKeyboard.filterKeySequenceBindings(WorkbenchKeyboard.java:564) at org.eclipse.ui.internal.keys.WorkbenchKeyboard.access$3(WorkbenchKeyboard.java:506) at org.eclipse.ui.internal.keys.WorkbenchKeyboard$KeyDownFilter.handleEvent(WorkbenchKeyboard.java:122) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Display.filterEvent(Display.java:982) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:927) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:952) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:937) at org.eclipse.swt.widgets.Widget.sendKeyEvent(Widget.java:965) at org.eclipse.swt.widgets.Widget.sendKeyEvent(Widget.java:961) at org.eclipse.swt.widgets.Widget.wmChar(Widget.java:1275) at org.eclipse.swt.widgets.Control.WM_CHAR(Control.java:3346) at org.eclipse.swt.widgets.Table.WM_CHAR(Table.java:4495) at org.eclipse.swt.widgets.Control.windowProc(Control.java:3246) at org.eclipse.swt.widgets.Table.windowProc(Table.java:4491) at org.eclipse.swt.widgets.Display.windowProc(Display.java:4025) at org.eclipse.swt.internal.win32.OS.DispatchMessageW(Native Method) at org.eclipse.swt.internal.win32.OS.DispatchMessage(OS.java:1923) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2966) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1914) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1878) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:419) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:95) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:78) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:92) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:68) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:400) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:177) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at org.eclipse.core.launcher.Main.invokeFramework(Main.java:336) at org.eclipse.core.launcher.Main.basicRun(Main.java:280) at org.eclipse.core.launcher.Main.run(Main.java:977) at org.eclipse.core.launcher.Main.main(Main.java:952)
