Not sure what caused this. Eclipse was hung and I had to restart. I had multiple splits in the editor content area and was maximising one particular spit. Error happend at that point. But that may not be the real cause. ----------------------- log ---------------------------- Error 2005-09-27 16:53:34.111 Unhandled event loop exception Error 2005-09-27 16:53:34.181 java.lang.NullPointerException java.lang.NullPointerException at org.eclipse.ui.internal.PartSashContainer.dropObject(PartSashContainer.java:1175) at org.eclipse.ui.internal.PartSashContainer$SashContainerDropTarget.drop(PartSashContainer.java:131) at org.eclipse.ui.internal.dnd.DragUtil.performDrag(DragUtil.java:131) at org.eclipse.ui.internal.FastViewBar.startDrag(FastViewBar.java:551) at org.eclipse.ui.internal.FastViewBar.startDraggingFastView(FastViewBar.java:527) at org.eclipse.ui.internal.FastViewBar$1.handleEvent(FastViewBar.java:106) at org.eclipse.ui.presentations.PresentationUtil.handleMouseMove(PresentationUtil.java:96) at org.eclipse.ui.presentations.PresentationUtil.access$4(PresentationUtil.java:89) at org.eclipse.ui.presentations.PresentationUtil$2.handleEvent(PresentationUtil.java:61) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:884) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3194) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:2823) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:1755) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:1719) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:368) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:143) at org.eclipse.ui.internal.ide.IDEApplication.run(IDEApplication.java:106) at org.eclipse.core.internal.runtime.PlatformActivator$1.run(PlatformActivator.java:226) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:377) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:164) 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:338) at org.eclipse.core.launcher.Main.basicRun(Main.java:282) at org.eclipse.core.launcher.Main.run(Main.java:977) at org.eclipse.core.launcher.Main.main(Main.java:952) ---------------------- end ---------------

Might be somehow related to bug 110354
When you say 'maximizing one particular split' what do you mean? The callstack you got indicates that you were in a Drag and Drop operation (as opposed to moving a splitter or maximizing a tab...). We already know that this can be caused by dragging from the 'Fast' bar (see Kim's comment) and I'm trying to figure out if this is the same problem (or whether we're more hosed than I thought...;-).
As I had mentioned I am not sure. May be by mistake I clicked and dragged something while maximising a split. I tried multiple splits in the content area - minimizing / maximizing them and could not recreate the problem.
We've already committed a fix for bug 110354 which solves both the fast view issue and should also solve this one (there were two failure paths and we've fixed both). I'll mark this as a dup but please re-open if your problem still occurs after getting a recent (i.e. today's) version. *** This bug has been marked as a duplicate of 110354 ***
