Some problems encountered after switching to the latest Oxygen and Red Deer bits:

https://issues.jboss.org/browse/JBIDE-25003 jbosstools-base test failures - need to switch to Red Deer 2.0
https://issues.jboss.org/browse/JBIDE-25002 jbosstools-server test failures - need to switch to Red Deer 2.0

If your project uses JBoss Red Deer 1.2, you'll also need to migrate to Eclipse Red Deer 2.0 as soon as possible.

Cheers,

Nick
