Hi All,
Please review fix for the below bug: Bug: https://bugs.openjdk.java.net/browse/JDK-8190456 Webrev: http://cr.openjdk.java.net/~akolarkunnu/8190456/webrev.00/ This issue observed during SBR(Same Binary Run) execution of client sanity tests. Same exception observed from test case sanity/client/SwingSet/src/DialogDemoTest.java also. It is a random failure, observed 2 times in 1000 iterations. In ComboBoxDemoTest, it is happening while changing the selection on a combo box. In DialogDemoTest, it is happening during button press. Fix: As currentEvent is a WeakReference, added null check for dispatchThread use case also, similar to fxAppThreadIsDispatchThread use case. Regards, Muneer
