Interesting... do you have any recommended reading on that, Graham?
Love these urban-legend types of warnings (don't flash your
headlights...).
I think Graham is referring to a bug in the 1.4.2 line of JVMs where
under certain circumstances, the HotSpot compiler trips over the garbage
collector, and causes mysterious VM aborts. I believe there have been
fixes in 1.4.2_06 and 1.4.2_07, and also in 1.5.0_01.
It's triggered more easily in an HT or MP machine, but the important
thing is that it can also be tripped on non-HT, single-processor
machines (though much more rarely).
