Hello, AWT Team. Please review the fix for the issue: https://bugs.openjdk.java.net/browse/JDK-8024158 The fix is available at: http://cr.openjdk.java.net/~pchelko/8024158/webrev.00/
The problem: Appkit thread could not have an AppContext, so we cannot call KeyboardFocusManager. getCurrentKeyboardFocusManager on it. The solution: use the Window AppContext to get the KeyboardFocusManager. With best regards. Petr.
