Bug 42367 StyledText - StringIndexOutOfBoundsException in StyledTextRenderer
Reported: 2003-09-02 05:38:54 | Status: resolved fixed

200308281813 When hovering over the quick diff ruler to display the diff hover. Not reproducable, but consistently failing for a certain hover (I suspect an empty hover message, but not sure). java.lang.StringIndexOutOfBoundsException: String index out of range: -1 at java.lang.Throwable.<init>(Throwable.java) at java.lang.Throwable.<init>(Throwable.java) at java.lang.StringIndexOutOfBoundsException.<init>(StringIndexOutOfBoundsException.java:67) at java.lang.String.substring(String.java) at org.eclipse.swt.custom.DisplayRenderer.getStyledTextWidth(DisplayRenderer.java) at org.eclipse.swt.custom.StyledTextRenderer.getTextWidth(StyledTextRenderer.java) at org.eclipse.swt.custom.StyledText$ContentWidthCache.contentWidth(StyledText.java) at org.eclipse.swt.custom.StyledText$ContentWidthCache.calculate(StyledText.java) at org.eclipse.swt.custom.StyledText.computeSize(StyledText.java:2116) at org.eclipse.swt.layout.GridLayout.calculateGridDimensions(GridLayout.java) at org.eclipse.swt.layout.GridLayout.computeLayoutSize(GridLayout.java) at org.eclipse.swt.layout.GridLayout.computeSize(GridLayout.java) at org.eclipse.swt.widgets.Composite.computeSize(Composite.java) at org.eclipse.swt.widgets.Control.computeSize(Control.java) at org.eclipse.jdt.internal.ui.text.java.hover.SourceViewerInformationControl.computeSizeHint(SourceViewerInformationControl.java:315) at org.eclipse.jdt.internal.ui.text.CustomSourceInformationControl.computeSizeHint(CustomSourceInformationControl.java:70) at org.eclipse.jface.text.AbstractInformationControlManager.internalShowInformationControl(AbstractInformationControlManager.java:708) at org.eclipse.jface.text.AbstractInformationControlManager.presentInformation(AbstractInformationControlManager.java:677) at org.eclipse.jface.text.AbstractHoverInformationControlManager.presentInformation(AbstractHoverInformationControlManager.java:423) at org.eclipse.jface.text.AbstractInformationControlManager.setInformation(AbstractInformationControlManager.java:224) at org.eclipse.jface.text.source.AnnotationBarHoverManager.computeInformation(AnnotationBarHoverManager.java:97) at org.eclipse.jface.text.AbstractInformationControlManager.doShowInformation(AbstractInformationControlManager.java:661) at org.eclipse.jface.text.AbstractHoverInformationControlManager$MouseTracker.mouseHover(AbstractHoverInformationControlManager.java) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2036) at org.eclipse.ui.internal.Workbench.run(Workbench.java:2019) at org.eclipse.core.internal.boot.InternalBootLoader.run(InternalBootLoader.java:858) at org.eclipse.core.boot.BootLoader.run(BootLoader.java:461) at java.lang.reflect.AccessibleObject.invokeL(AccessibleObject.java:207) at java.lang.reflect.Method.invoke(Method.java:271) at org.eclipse.core.launcher.Main.basicRun(Main.java:295) at org.eclipse.core.launcher.Main.run(Main.java:751) at org.eclipse.core.launcher.Main.main(Main.java:587)
