Eclipse freeze opening e(fx)clipse based plugin view (Linux) [message #1765530]

Dear developers.

we are working on an Eclipse based tool http://controlsystemstudio.org/ . After upgrading the application to Neon and the latest version of E(fx)clipse 2.4.0 we're experiencing a total JVM freeze when opening a plugin view that uses JavaFX controls.

The same view opens normally on Windows.

Since we don't see any errors or anything, just a freeze, I was wondering if you have any suggestions how to go about finding the cause of the freeze.

Are there any E(fx)clipse settings that we may use to increase the logging? Anything else that may give us an error message before the freeze? If we manage to get a core dump, is there anyone that can take a look at it?

Thanks for your answers and best regards, Miha

My guess is that with neon you run on gtk3 by default and javafx8 only supports gtk2. On java8 you need to force SWT to Gtk2 with JDK9 Gtk3 is supported by JavaFX

Thank you for your answer. This is probably the case, since we're on GTK3.

Hi did it work for you?

In our application the Linux version (that forces to use Gtk2) get locked from time to time at startup. Yet we don't know what's the reason, but if the workbench state persistence is disabled then it works. I really do not have any idea of what's happening, in Mac and Windows it works well.
