JDK adventures

[Paul E Johnson]

I just found out my JDK was not the newest. Here's how!

I wrote a java program that is slow, tried profiling on an SMP Linux 7.0
system:

$ javaswarm -prof ObserverSwarm
#
# HotSpot Virtual Machine Error, Internal Error
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
#
# Error ID: 4D555445583F4C494E55580E4350500104
#
# Problematic Thread: prio=1 tid=0x804e1f0 nid=0x400 runnable
#

I went to the Sun bug site and they say they fixed this bug, and I
noticed my jdk was 1.3beta on this system, so I grabbed their newest jdk
and tried got the same:

$ javaswarm -prof ObserverSwarm
#
# HotSpot Virtual Machine Error, Internal Error
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi
#

/usr/bin/javaswarm: line 1:  2272 Aborted

I'll try the same on a one-processor system when I go home, but what
else do you think might be wrong?
After downloading/replacing jdk1.3, am I supposed to recompile Swarm?
