Description Ivo Bek CLA 2013-04-19 08:18:01 EDT 
I use JBDS 6.0.1.GA installation with following plugins:

EMF Validation Framework SDK
BPMN2 modeler
Drools and JBPM plugin

I use Archlinux x64, I even tried different java development kits - jdk1.6.0_43, jdk1.7.0, openjdk 1.7 but nothing helped. At work I use Fedora, where the bpmn2 modeler worked, so I guess the bug depends on OS - Archlinux.

I only open a bpmn process from jbpm example project and the eclipse instance freezes.

sample bpmn process

After I open a bpmn process and restart jbds, Error log contains following warnings:

Constraint "org.eclipse.bpmn2.modeler.core.validation.warning" could not find target EMF type "BPMNDiagram."

Constraint "org.eclipse.bpmn2.modeler.core.validation.error" could not find target EMF type "BPMNDiagram."

Unable to reproduce this error with the attached sample process. Can you please retest with latest version?
Comment 3 Ivo Bek CLA 2013-05-08 09:28:11 EDT 
Hi Robert,

I updated bpmn2 modeler but nothing changed. Still freezes when I open any bpmn2 process. Maybe it's just a problem of some system library because I didn't update system some time. So if it works well for you on Archlinux that's fine and I will try to update everything I can.
Comment 4 Robert Brodt CLA 2013-05-08 09:52:58 EDT 
Thanks Ivo. I have not tested with Archlinux yet. I'll have to create a new VM and install the OS. This will probably take some time because I am currently working on graphiti 0.10.0 migration for kepler.

If you have some time, it would help if you could provide some more details about where eclipse seems to be getting stuck.

I have tested with ArchLinux 2013.07.01 in a VMWare(R) VM and verified that this is indeed a problem. After debugging, it looks like eclipse is blocking in a native library method named OS.gtk_enumerate_printers. After some research, this appears to be related to https://bugs.eclipse.org/bugs/show_bug.cgi?id=153936. A similar problem was reported for Open Office on ArchLinux here https://bbs.archlinux.org/viewtopic.php?id=50439 so, I'm not sure if this is specific to eclipse or ArchLinux in general.

I also tried simply printing a text file in eclipse and this produced the same type of behavior. I'm not sure how to proceed, but this is not a BPMN2 Modeler specific problem...
Comment 6 Ivo Bek CLA 2014-04-27 10:24:41 EDT 
To workaround the problem it is enough to add "-Dorg.eclipse.swt.internal.gtk.disablePrinting" into studio/jbdevstudio.ini as it is mentioned here https://bugs.eclipse.org/bugs/show_bug.cgi?id=153936

Not more reproducible.
Comment 8 Jozef Marko CLA 2016-09-16 04:45:42 EDT 
Verified on   BPMN2 Modeler - 1.2.5.Final-v20160831-1132-B114
