Hi all, Reference ticket: https://issues.jboss.org/browse/JBIDE-12277 We are hitting this issue for CI jobs: https://bugs.eclipse.org/bugs/show_bug.cgi?id=376560 SWT is incompatible with some older gtk versions, such as the one that are available on Jenkins slaves that use RHEL 4. It seems like *Eclipse 4.2 (and everything based on it) don't work on RHEL 4* because of its old gtk version. How should we react? Testing only on RHEL 5+ and dropping support for RHEL 4 seems to be the easiest way to go.
