The backport of the following fix, which removes sun.misc.GThreadHelper, will break all FX interop applications, even if GTK2 is used:

https://bugs.openjdk.java.net/browse/JDK-8154546 : Retire sun.misc.GThreadHelper

The FX GTK port still uses that class, so the class needs to be left in until after the FX support for GTK 3 has been backported.

Hi All,


Please review the patch for 8u-dev backport for JDK-8145547. It adds conditional support for gtk3. 

The original fix does not apply cleanly as few changes were done  in jdk9 before the gtk3 support was added, major once being HYPERLINK "https://bugs.openjdk.java.net/browse/JDK-8025815"JDK-8025815, HYPERLINK "https://bugs.openjdk.java.net/browse/JDK-8014212"JDK-8014212 and HYPERLINK "https://bugs.openjdk.java.net/browse/JDK-8137571"JDK-8137571
