If the CPU is maxed out, the thread dump will provide lightweight process numbers. Using a tool like "prstat -L" on Solaris, you can figure out which lightweight process (thread) it is, and at least confirm that it is the GC thread. the output from prstat is indexed at 1, but the stack dump is indexed at 0, so you need to either add one to the stack dump lwp id, or subtract one from the prstat output.
I'm sure there is an equivalent command for prstat in other operating systems, but I do not know what it is.
