Well, yes I agree this may be unusual, although I don't believe it it illegal. 

It seems to me the JCA is making an incorrect assumption that a particular connection instance can't be both a Connection and an XAConnection. It just so happens up to now JBM is the only provider that implements it this way.

Having said all that, to get this fixed quickly, it should be fairly trivial for us to make the change in JBM to separate out the Connection and XAConnection classes. So I suggest we do that.
