Can you please try to deploy the community version, in order to see if this is a product specific issue? https://github.com/droolsjbpm/jbpm-dashboard/tree/6.0.x/jbpm-dashboard-distributions By the way, what WAS version are you using? PD: Unfortunately, right now, I can test on my local laptop since my WAS evaluation license has expired.
The latest dashbuilder product build works with no issues. No classloader changes are required in the app settings to get it working. So we can close this BZ. See https://bugzilla.redhat.com/show_bug.cgi?id=1095363
