Denis Golovin updated JBIDE-5688:
---------------------------------

    Priority: Minor  (was: Major)


The reason why it is happened is stop method implemented like 

	/*
	 * (non-Javadoc)
	 * @see org.eclipse.ui.plugin.AbstractUIPlugin#stop(org.osgi.framework.BundleContext)
	 */
	public void stop(BundleContext context) throws Exception {
		ResourcesPlugin.getWorkspace().removeResourceChangeListener(resourceChangeListener);
		plugin = null;
		super.stop(context);
	}


stopping one plugin doesn't mean other plug-ins cannot call static methods after that.

it seems that SeamELValidator invokes SeamCorePlugin.getDefault() after seam core plug-in is stopped.

Solution would be removing line

plugin = null;
