Description of problem: See linked issue.
Please note that this seems to be an issue in JBDS 8 itself.
This is not an issue in the editor. Everything works fine when the following system property is set. # Don't use GTK 3 export SWT_GTK3=0 Can we document this?
I have set this as a note in JBoss Central topic where Eclipse is first started [1]. Moving this to ON_QA. [1] https://documentation-devel.engineering.redhat.com/site/documentation/en-US/Red_Hat_JBoss_BPM_Suite/6.1/html-single/Getting_Started_Guide/index.html#JBoss_Central
