System.loadLibrary() core dump

I've just been handed this problem to look at.
I'm looking for some comments and suggestions on this.
I'm trying to decide what actions I need to take.

Thanks


JAVA/Solaris related.

In a nutshell, we have been attempting to use JAVA 1.3.0 and/or 1.3.1 on Solaris 2.8 wanting to upgrade from the JAVA 1.2.X versions. Thing is, we are unsuccessful in attempts to run on the 1.3.X versions due to the VM process aborting:

Example:
{hyperion}19%java LoadLib
Before Load Lib...
Abort (core dumped)

After running with truss it appears that the problem occurs during the loading of one of our shared libraries. Thus I created a new test, LoadLib, which only calls System.loadLibrary("ourlib") and immediately fails with the core dump.

I have added the required Solaris 2.8 patches specified by the JAVA installation documents and thing are still not working.

This behavior is strange to say the least since we can run successfully with the 1.2.x versions and NOT the 1.3.x versions.

Anyone have an issue with loadLibrary of the sort or have a clue what may be happening?

More Information:
I can compile and link my libs on Solaris 2.8 with JDK 1.2.x and everything works fine.

The call to System.loadLibrary() subsequently "core dumps" deep within the call stack of a JVM native method call, so there wouldn't be an exception to catch. You can check it out yourself, I've included the call stack I get from dbx.

The LD_LIBRARY_PATH is set properly.


Here is the class which gets run:

public class LoadLib {

static {
System.out.println("LD_LIBRARY_PATH=" + System.getProperty("java.library.path"));
System.out.println("Before Load Lib...");
try {
System.loadLibrary("com_devkit");
}
catch (Throwable t) {
System.out.println("Caught this..." + t.toString());
t.printStackTrace(System.out);
}

System.out.println("After Load Lib...");
}

public static void main (String[] args) {
System.out.println("Done!");
}
}

Here is the stack from "dbx":
Exception of type int {assumed} is unexpected
