It does. You can think of RAFContainer4 as an overlay on RAFContainer
- it only comes into play on 1.4+ JVMs: "if( JVMInfo.JDK_ID >=

The current code is quite cowardly, and falls back to the old
version if something goes wrong. =)

Thanks for the description of the benchmark, if I'm bored I might smash
together something based on it, but as I'm supposed to be preparing for
the exams next week instead of coding now that'll probably have to wait.
I've procrastinated enough as it is. ;)

I've put the patch in Jira (DERBY-801) after a little cleanup and
running storeall.  Caveat: It needs some more work to be worthy of
consideration for the trunk, but at least it passes storeall. =)

Anyone interested is welcome to beat the c!!p out of it, maybe we can
turn it into something useful together? =)

My opinions may have changed, but not the fact that I am right!
