A DESCRIPTION OF THE PROBLEM :
When attempting to launch the Sun One Server under our application, DevPartner Java we get a HotSpot crash.

We have reduced this issue to a collision between the -XX:+AggressiveHeap
and JVMPI memory events. We can crash the JVM using a standalone JSE source
file and the hprof profiler. We can reproduce this issue on Windows and on
Solaris using the standalone 1.4.2 JVM. The following analysis is for
Windows XP using Sun JDK 1.4.2_09. Please let us know if there is a fix for
this, as SunOne 7.0 2004Q2UR4 sets the -XX:+AggressiveHeap by default
therefore giving the appearance that our profiler's memory analysis
capability is the cause of the JVM crash. Our customer uses SunOne 7.0
2004Q2UR4 over JDK 1.4.2_08, and we are instructing them to remove the
-XX:+AggressiveHeap switch as a workaround.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Did not try

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Did not try

SOURCE CODE FOR TEST CASE :
class HWorld
{
        public static void main(String args[])
        {
           System.out.println("Hello World!");
        }
}

STEPS TO REPRODUCE :
1. javac HWorld.java
2. java -XX:+AggressiveHeap -Xrunhprof:heap=sites -showversion -cp . HWorld
[Both -XX:+AggressiveHeap -Xrunhprof:heap=sites are needed to reproduct the failure.}
