ug 26 2005 16:11:55 by unknown with unknown Workshop:0x550


FULL OS VERSION :
SunOS ws1360 5.8 Generic_117000-05 sun4u sparc SUNW,Sun-Blade-1500
SunOS ws1474 5.9 Generic_118558-11 sun4u sparc SUNW,Sun-Blade-1500
SunOS ws2200 5.10 Generic_118822-19 sun4u sparc SUNW,Sun-Blade-1500


A DESCRIPTION OF THE PROBLEM :
Trying to run a simple demo application with JacORB causes HotSpot to dump core (SIGSEGV) The problem remains even when using /usr/lib/lwp/libthread rather than plain old (bad) libthread.so


THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run a JacOrb test (simple client /server) on a Solaris box

In my simple test, I run it for 150000 iterations, plus 80000 warmup iterations (to enable
native compilation). After only a few seconds, the JVM exits with a SIGSEGV
when trying to compile org.jacorb.orb.Delegate.request(Lorg/omg/CORBA/Object;Ljava/lang/S
tring;Z)Lorg/omg/CORBA/portable/OutputStream; (240 bytes)

This was not present in 1.5.0_02
