Hi Murali, Kevin, Alexander,
Please review the webrev : http://cr.openjdk.java.net/~arajkumar/ankit/8133775/webrev.00/ JBS: https://bugs.openjdk.java.net/browse/JDK-8133775 Changes: 1) Made "checkEventThread()" function public to make it accessible to JSObject class which is in different package and is not a derived class of Invoker. 2) Added check to throw exception instead of JVM crash if functions are called from non-jfx thread. Reference : https://docs.oracle.com/javafx/2/api/javafx/scene/web/WebEngine.html Verified on Linux 64 machine with changes , exception is being thrown instead of JVM crash. On Windows 64 JVM doesn't crash previously, with code changes exception will be thrown. Regards, Ankit
