1.4.2-05 or -07 JVM dumps core immediately, when trying to run w/ jprofiler
(www.jprofiler.com) and -XX:+AggressiveHeap.

This was found when trying to profile "Sun Java System Application Server 7
2004Q2UR1", which is run w/ -XX:+AggressiveHeap by default.

The problem is strictly reproducible:

1. Testcase
-----------
% more HelloWorld.java
            public class HelloWorld {
                public static void main(String[] args) {
                  System.out.println("Hello World!\n");
                }
            }

2. Compile and run
------------------
% /j2sdk1.4.2_07/bin/javac HelloWorld.java
%
% setenv LD_LIBRARY_PATH $PWD/jprofiler3/lib:/usr/lib

/net/redback/data/j2sdk1.4.2_07/bin/java -Xint -Xbootclasspath/a:/lab/Calls/AppSrv/javacrash/jprofiler3/bin/agent.jar -Xrunjprofiler:port=8849 -XX:+AggressiveHeap HelloWorld

Some permanently running application would be needed here for profiling, but just
to show, that it's working fine.
