Description Sravan Kumar Lakkimsetti CLA 2014-03-27 06:16:28 EDT 
SWT_AWT bridge is loading gtk2 libraries also. and when you run the snippet135, the application(snippet135) is hanging. 

OS details: Ubuntu 13.10 GTK 3.8.6 and GTK 2.24.20

Link for the snippet http://git.eclipse.org/c/platform/eclipse.platform.swt.git/tree/examples/org.eclipse.swt.snippets/src/org/eclipse/swt/snippets/Snippet135.java

This is also a problem for JavaFX that uses GTK2 as well.

Just for the sake of clarity, GTK+ 2 is loaded because AWT depends on the same and not by the SWT_AWT bridge itself. The GTK+ website [1] does mention the problems caused when GTK+ 2 and GTK+ 3 libraries are loaded by the same process.

Comment 3 Alexander Kurtakov CLA 2014-04-02 11:19:11 EDT 
AWT is supposed to load GTK only if Gnome L'n'F is set as default IIRC. Can someone please verify whether the bridge is crashing with another L'n'F ? My testing shows this worsk. Plain awt snippets should work too. Regarding JavaFX I have no idea how/why it loads gtk.
Comment 4 Sravan Kumar Lakkimsetti CLA 2014-04-03 07:45:39 EDT 
I have tested with the following JREs on Ubuntu 13.10 64 bit

1. OpenJDK Runtime Environment (IcedTea 2.4.4) (7u51-2.4.4) This fails in all Look and Feel modes
2. IBM JRE build pxa6470_27_20131115_04 This works in all modes except GTK Look and feel
3. Oracle JRE 7 build 1.7.0_51-b13 This works in all modes except GTK Look and feel
4. Oracle JRE 8 build 1.8.0-b132 This works in all modes except GTK Look and feel

By the way in Ubuntu the default JRE is OpenJDK Runtime Environment. This fails
Comment 5 Arun Thondapu CLA 2014-04-03 08:18:48 EDT 
I can confirm that I do not have the problem too using IBM/Oracle JREs. It seems to be a OpenJDK/JRE only problem.
Comment 6 Alexander Kurtakov CLA 2014-04-03 09:02:47 EDT 
It seems to be OpenJDK on Ubuntu problem.
On RHEL 7 with OpenJDK 1.7 I can run the snippet just fine with default and Nimbus LaF just fine and it crashes with Gtk LaF as all other JREs.

I submitted a bug report to OpenJDK. The bug report id is JI-9011514

FYI, this was resolved in the 2.5.0 release of IcedTea: http://bitly.com/1l7n3Qq
