Bug 320790 NPE in ContributionsAnalyzer
This is the I20100723-2001 build and I somehow managed to get into a state where all context menus result in this NPE! java.lang.NullPointerException at org.eclipse.e4.ui.internal.workbench.ContributionsAnalyzer.gatherMenuContributions(ContributionsAnalyzer.java:97) at org.eclipse.e4.ui.workbench.swt.modeling.MenuServiceFilter.showMenu(MenuServiceFilter.java:134) at org.eclipse.e4.ui.workbench.swt.modeling.MenuServiceFilter.handleMenu(MenuServiceFilter.java:117) at org.eclipse.e4.ui.workbench.swt.modeling.MenuServiceFilter.handleEvent(MenuServiceFilter.java:103) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Display.filterEvent(Display.java:1031) at org.eclipse.swt.widgets.Display.sendEvent(Display.java:3775) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1367) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1390) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1371) at org.eclipse.swt.widgets.Menu.menuWillOpen(Menu.java:689) at org.eclipse.swt.widgets.Display.windowProc(Display.java:5030) at org.eclipse.swt.internal.cocoa.OS.objc_msgSendSuper(Native Method) at org.eclipse.swt.widgets.Display.applicationNextEventMatchingMask(Display.java:4483) at org.eclipse.swt.widgets.Display.applicationProc(Display.java:4739) at org.eclipse.swt.internal.cocoa.OS.objc_msgSend(Native Method) at org.eclipse.swt.internal.cocoa.NSApplication.nextEventMatchingMask(NSApplication.java:85) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3271)
