Hehehe :) You're going down hard-core on the VM :)
Well, I don't think you'll be actually able to TRAP a SEGV signal, I mean,
that signal means "segment violation" and it's the worst thing you can
possibly try to debug...
What I think is happening is that the VM itself (for debugging purposes, I
believe with the Debugging Native Interface), tries to set a handler to
SIGSEGV itself, and if it has already been set, it will just panic...
Aka, all it means is "don't mess around too much with that" :)
I don't know, though! I should have to go and look into the Hotspot
sources...
So far the same code you wrote works with SIGHUP, SIGKILL and SIGUSR?...
