Yes the query is OK (conform to the spec) and the parser is OK too.

I don't know myself : (unspecified in the spec) but the parser is OK too.

I just mean that I have tried the syntax in my application (quickly) and redeploy to 
test. I had no errors, so I can say that the parser is OK. But I don't test the query 
and look at the results (because I'm not in such a configuration). If you do that, 
tell me if it works.
For testing, I do the same way as you, just don't need to stop and restart JBoss, you 
can do a hot deployment while running.
