It seems the patch for https://bugs.openjdk.java.net/browse/JDK-8248532 causes a crash, as it attempts to call a method selector on a class for an instance method (- keyboardInputSourceChanged). It was not observed in 10.14 but seen in 10.15 or later. It resulted in crash as we are passing [AWTView class] as an instance to the notification observer but notification function keyboardInputSourceChanged is not a member function. Modified the code to make that function a class-level function so that it does not crash. mucommander.app, JDK-8214578 testcase worked with this change.
