Hello, Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8164321 webrev: http://cr.openjdk.java.net/~ssadetsky/8164321/webrev.00/The issue is caused by concurrent XLib access form FX and AWT toolkit threads in case of GTK3. To fix the issue wrapping by gdk_threads_enter/gdk_threads_leave is added to JDK GTK+ LnF GTK3 implementation. Since FX GTK3 implementation uses gdk_threads_enter/gdk_threads_leave as well this will make GTK3 XLib calls serialized.
