This bug was filed for JDK 7. Do we need to plan backport of JDK-8051030 to JDK 7 or is it ok to ignore it for now?

fix is quite simple - when running javaws with applet - we use plugin and failure is in Plugin2Manager.destroyAppContext when stopListener is null. just check for null before calling stopFailed: if (stopListener != null) { stopListener.stopFailed(); }
