Martin> But I think I will - that'll save me some 20-40 ms, as well.
BTW, a patch to do this would help the trunk as well -- it is a
generic IdentityHashMap improvement.  I'm all for it :-)

Me too! I'll go for it...

Nevertheless, just fixing the stupid old bug I have now saved ~150ms in each GC, resulting in GC times of 240-280 ms instead! Implementing the new null-approach it will be even more beautiful - I'm so thrilled! And ofcourse fixing this also saves me some 500-600 kb of precious ram (/14mb)!

But to finish this thread, thanks guys - you know who you are (I do: _Bryce, David, Hans, Rutger, and Tom_ [others?])!

BR,
 Martin
