Hi, Please review a fix for 8014264: The applet pathguyTimeDead throws java.lang.NullPointerException in java console once click drop-down check box. The problem here is that for applets prePostEvent is called within ThreadGroup that, by design, has no AppContext associated with it. So, when the code in XChoicePeer/XListPeer prePostEvent implementation calls EventQueue.invokeLater, it results in NPE because there is no EQ for this ThreadGroup. The fix is not to use invokeLater, but to manually create InvocationEvent to ensure that target's AppContext would be used to find an EQ for the event to go into.
