Hey Mike,

I just tried to reverse engineer a 6.2 teiid vdb, because I thought your central thrust here was incorrect and that we had everything we needed already, and it fails. The tooling can't find our dialect. It's in all the lists, but the classes are not getting found.

I believe this to be a defect, and that with the latest release of JBossTools you should be able to reverse engineer a Teiid VDB. I'll see about tracking down the issue and logging a Jira.
