Problem running Java program that calls methods in a Windows C++ DLL via a JNI wrapper.......

Am having a problem running an Eclipse Java program in the IDE on Windows XP that calls Windows C++ methods in a Windows DLL via JNI. The JNI wrapper was developed using the SUN SDK. When we run the java program using the SUN JVM it all works well; when we attempt this using the JVM available with IBM Websphere we have the following problem when we attempted to make the first C++ method call:

JVMDG217: Dump Handler is Processing Signal 11 - Please Wait.
JVMDG303: JVM Requesting Java core file
JVMDG304: Java core file written to C:\EclipseWorkspace\AppName\javacore.20060626.095514.392.txt

and in the dump file found the following:

I believe you'd better open PMR with IBM since it is IBM WAS JVM issue.

Thanks Andy,

Do you know of any specific information on this issue? I did some research on the internet and it seems other people have run into related problems but not this specific one. I guess I am wondering if it has already been reported and there is some known workaround or patch. If I don't find something soon a PMR will be opened.

Did you analyze this Java Core dump with IBM Thread analyzer ?

Check following URL ( You will also find URL to download IBM ThreadAnalyzer tool which read java core dump and analyze it ):

Good Luck.

try running with java -Xcheck:jni, it helps you find out native problems
