I've been developing and "porting" Java apps on Mac OS X and it's been
a true pleasure. Java on Apple seems top-notch.
Except that one app I'm running can quite reliably cause a kernel
panic. I'm narrowing down the module that's causing it so I can try to
show you a small test case, but before I spend any more time, I'm
wondering if this is old news. (I'd search the archives, if the
feature existed!)
Anyone else out there suffering? Another interesting note is that this
occurs only on my dual G5, not my iBook G4. Perhaps related to
threading on multiple CPUs?
The panic log usually looks like the following, if you're curious, or
happen to be an Apple employee:
