Bug 29500 Cannot cancel organize imports
After selecting organize imports on my project (to reduce the 4175 warnings about unused imports I got when I upgraded to 2.1 M4), I decided that maybe this was going to take longer than I thought, so I tried to cancel the action. The cancel button on the dialog didn't to do anything. I can repeat this at will with my project. I'm using Sun's JDK 1.4.1_01 on Debian GNU/Linux, SWT/Motif.

		if (monitor == null) {
			monitor= new NullProgressMonitor();

		monitor.beginTask(ActionMessages.getString("OrganizeImportsAction.multi.op.description"), cus.length); 
		try {
			IPreferenceStore store= PreferenceConstants.getPreferenceStore();
			String[] prefOrder= JavaPreferencesSettings.getImportOrderPreference(store);
			int threshold= JavaPreferencesSettings.getImportNumberThreshold(store);
			boolean ignoreLowerCaseNames= store.getBoolean(PreferenceConstants.ORGIMPORTS_IGNORELOWERCASE);
