Bug 61743 NPE in MessageDialog with null parent shell
I-build 2004-05-11 I have code that does the following: MessageDialog.openInformation(null, "Showing element", "Showning an integer of value: "+((Integer)match.getElement()).intValue()); This leads to a null pointer with the follwing stack trace: Thread [main] (Suspended (exception NullPointerException)) MessageDialog.<init>(Shell, String, Image, String, int, String[], int) line: 126 MessageDialog.openInformation(Shell, String, String) line: 305 TestUIParticipant.showMatch(Match, int, int, boolean) line: 57 JavaSearchResultPage.showMatch(Match, int, int, boolean) line: 153 AbstractTextSearchViewPage$9.run() line: 723 <snip> The API doc for MessageDialog say that I'm allowed to pass in null for the parent shell.
