In short - no, but do tell if you find some :-)

The problem before was that you can't mix GTK2 & 3 in the same application, so SWT for example that is using GTK3 would crash and burn. With the addition of dynamic loading of GTK we can at least avoid that issue - at least as long as you tell the app which version to use. I have a task to investigate detecting if a version is already in use <https://bugs.openjdk.java.net/browse/JDK-8156491>, but that has some portability issues and might not make the final product. I am not aware of any reason why there would be an issue - unless there is something with the GTK event loop.

Let me know if you give it a try.
