Root-cause: Problem is due to the following statement in `void PluginWidgetJava::updatePluginWidget()` jobject obj = platformWidget(); platformWidget method returns temporary JGObject as a value and it���s life time is restricted with in the same line. Proposed solution: Change the `obj` type to JLObject, so that it will hold the ref object as local variable in the function scope. JLObject obj = platformWidget(); webrev: http://cr.openjdk.java.net/~arajkumar/8206899/webrev
