Re: JPL on RedHat

I was able to finally get JPL running with JDK 1.2.2 I had to go in to the
Makefile and tweak it so that everywhere that it said green_threads read
native_threads and it seems to work fine. I just have one more question is
there any way to get rid of this garbage:

SIGSEGV   11*  segmentation violation
    si_signo [11]: SIGSEGV   11*  segmentation violation
    si_errno [0]: Success
    si_code [0]: SI_USER [pid: 0, uid: 0]
	stackpointer=0xbffff56c
