Too much Java overhead on one database and PL/J isn't that stable.
I've run into several crash problems with it before.

While tired, you're still correct :)

Not really, both require a JVM so the same licensing still applies.

I'm being objective here, and PL/J is not nearly as stable or
well-maintained... that means a lot to me or to anyone who looks at
using a Java PL.  Do we intend to ship both and say that one is less
capable?  Have you used either of them?  Don't get me wrong, I like
PL/J in concept... but it's just not even close to production-ready
yet.  I know of no one using PL/J in production and about 40 or so
people using PL/Java.

Again, I don't believe so.  I'd like to hear how Dave thinks so, though.
