Hello,

If a RuntimeException is thrown in the MultiPageEditorPart.init() method, then the ComptaibilityEditor is null in the WorkbenchPage#busyOpenEditor() method causing a NPE and the real exception is masked.

Here the stacktrace :
java.lang.NullPointerException
	at org.eclipse.ui.internal.WorkbenchPage.busyOpenEditor(WorkbenchPage.java:3112)
	at org.eclipse.ui.internal.WorkbenchPage.access$22(WorkbenchPage.java:3020)
	at org.eclipse.ui.internal.WorkbenchPage$8.run(WorkbenchPage.java:3002)
	at org.eclipse.swt.custom.BusyIndicator.showWhile(BusyIndicator.java:70)
	at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2998)
	at org.eclipse.ui.internal.WorkbenchPage.openEditor(WorkbenchPage.java:2962)


Regards,
Arnaud
