Build: I20101119-1108 4.1 SDK Whenever my mouse moves over the area that can expand/collapse methods, I get the following error. The implications is that the GC handle == 0 (but I can't see how that can be possible given the code). Dani, what do you think? This is restricted to 4.1, I can't produce in 3.7. java.lang.IllegalArgumentException: Argument not valid at org.eclipse.swt.SWT.error(SWT.java:4072) at org.eclipse.swt.SWT.error(SWT.java:4006) at org.eclipse.swt.SWT.error(SWT.java:3977) at org.eclipse.swt.graphics.GC.setForeground(GC.java:3407) at org.eclipse.jface.text.source.projection.ProjectionAnnotation.drawRangeIndication(ProjectionAnnotation.java:106) at org.eclipse.jface.text.source.projection.ProjectionAnnotation.paint(ProjectionAnnotation.java:124) at org.eclipse.ui.texteditor.DefaultMarkerAnnotationAccess.paint(DefaultMarkerAnnotationAccess.java:256) at org.eclipse.jface.text.source.AnnotationRulerColumn.doPaint1(AnnotationRulerColumn.java:790) at org.eclipse.jface.text.source.AnnotationRulerColumn.doubleBufferPaint(AnnotationRulerColumn.java:541) at org.eclipse.jface.text.source.AnnotationRulerColumn.redraw(AnnotationRulerColumn.java:824) at org.eclipse.jface.text.source.projection.ProjectionRulerColumn$2.mouseMove(ProjectionRulerColumn.java:231) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java:205) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1258) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3539) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3160)

Please also fix bug 327837 while you're in that method.
The dispose call is no longer needed as the color will either be disposed by the engine or it's a system color. Fixed in HEAD > 20101119
