okey, normally we call that a PDE launched IDE or similar - RCP is often something very different ;)

well the threadstack you showed seemed to be inside the client - but yeah, that Future referenced in there
could for sure be blocking on ui thread.

And yes, for sure do not do these operations in the main ui thread - that will cause all kind of havoc.

That's Teiid Designer version, not JBoss Tools version.

Okey, so this is JBoss Tools 4 - targeting Juno, JBDS 6.

no problem - nice to see work is going on here - I thought it died out since noone followed up on
the last thread on the Teiid integration. I've revived that thread in case it was missed ;)
