org.guvnor.tools.Activator adds ResourceChangeListener, but doesn't remove it
-----------------------------------------------------------------------------

                 Key: JBIDE-6749
                 URL: https://jira.jboss.org/browse/JBIDE-6749
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: drools
    Affects Versions: 3.2.0.M1
            Reporter: Snjezana Peco
            Assignee: Kris Verlaenen


The following exception happens sometimes when exiting Eclipse (when running tests that remove projects on exit, for instance):

org.eclipse.swt.SWTException: Device is disposed
	at org.eclipse.swt.SWT.error(SWT.java:4083)
	at org.eclipse.swt.SWT.error(SWT.java:3998)
	at org.eclipse.swt.SWT.error(SWT.java:3969)
	at org.eclipse.swt.widgets.Display.error(Display.java:1249)
	at org.eclipse.swt.widgets.Display.asyncExec(Display.java:700)
	at org.guvnor.tools.ResourceChangeListener.deleteResources(Unknown Source)
	at org.guvnor.tools.ResourceChangeListener.resourceChanged(Unknown Source)
	at org.eclipse.core.internal.events.NotificationManager$2.run(NotificationManager.java:291)
	at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42)
	at org.eclipse.core.internal.events.NotificationManager.notify(NotificationManager.java:285)
	at org.eclipse.core.internal.events.NotificationManager.broadcastChanges(NotificationManager.java:149)
	at org.eclipse.core.internal.resources.Workspace.broadcastPostChange(Workspace.java:327)
	at org.eclipse.core.internal.resources.Workspace.endOperation(Workspace.java:1181)
	at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:45)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

The solution would be to add getWorkspace().removeResourceChangeListener(rcListener) to the Activator.stop() method.
