We are sortof inbetween 1.1 and 1.2, but in general are trying to get to 1.2.
I've communicated with Sean and it doesn't look like there should be
any problem getting his java.security stuff checked in..

TVT is going to release their new & improved JIT engine sometime soon..
As for garbage collection, Godmar has been working on that some, maybe
he can share some insights. Don't know if the new JIT supports conditional
JIT'ing or not.

Nothing's happened with this for a while.. volunteers very welcome.
In particular I'd like us to do both of the above.

I think Tim may have some ideas about this.. JDK 1.2 allows the VM to
assume that MONITORENTER/MONITOREXIT occur in pairs, in which case you
can optimize locking by keeping lock state on the stack, etc.

We are moving from pizza to Kopi soon because of license issues, but
it's not any faster. Personally I have jikes installed separately
and use it instead..

Not that I'm aware of..

That's great! We need more kaffe developers!! :-)
