FULL PRODUCT VERSION :
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0-b64, mixed mode)

FULL OS VERSION :
Linux logan 2.6.9-1.6_FC2 #1 Thu Nov 18 22:07:32 EST 2004 x86_64 x86_64 x86_64 GNU/Linux

A DESCRIPTION OF THE PROBLEM :
Using the SampleJVMTIAgent.c file from the article on JVMTI at http://java.sun.com/developer/technicalArticles/Programming/jvmti/, I generated a library and attempted to load it in Java with the -agentlib:SampleJVMTIAgent -agentpath:/usr/local/lib/libSampleJVMTIAgent.so options. This immediately crashed HotSpot with the given error report generated.

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: Yes

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
I run an sh script which performs the following statement:

exec /usr/java/jdk1.5.0/bin/java -agentlib:SampleJVMTIAgent -agentpath:/usr/local/lib/libSampleJVMTIAgent.so -Dorg.globus.wsrf.container.webroot=/usr/local/globus/ -DGLOBUS_LOCATION=/usr/local/globus -Djava.endorsed.dirs=/usr/local/globus/endorsed -classpath /usr/local/globus/lib/bootstrap.jar:/usr/local/globus/lib/cog-url.jar:/usr/local/globus/lib/axis-url.jar org.globus.bootstrap.Bootstrap org.globus.exec.service.test.scalability.ScalabilityTester logan:8080 Fork 0

EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected Behavior: HotSpot won't crash and program runs with output generated from the JVMTI agent
Actual Behavior: HostSpot crashes and the program doesn't run
