My work is going there to have an alternative to the sun's java with gnu java. And therefore I should implement some mechanics to handle SIGNALS in gnu java.

This might be one of the few appropriate uses of catching Mach exceptions directly (I believe Apple's adaptation of Sun's JVM does that as well). Those Mach exception APIs are considered SPIs in Mac OS X (so you're giving up some level of compatibility by doing it), but it often makes for a much better mechanism for dealing with these particular kinds of issues in a virtual machine environment.

I'm pretty sure Jim's right about the behavior of Apple's JVM. Microsoft's CLI implementation for Mac OS X uses Mach exceptions as well. The BSD signal APIs weren't sufficient for our needs. See <http://sharedsourcecli.sscli.net/source/browse/sharedsourcecli/pal/unix/exception/> if you want to see the Mach exception code in the shared source CLI.

Hope this helps,
