Getting an Exception in Native Libraries and generating Core.

[Krishna Kaswa]

Hi,
One of our test application is giving core dump after changing the JDK version from 1.3 to 1.4.1. It gives core dump only on hp11 machine and it doesn't create a core on hp11i machine (core dumps only on hpux11). Please find below the details and core trace on this. Can you pls advise on this?

We have already applied all the HP/JAVA recommended patches on this machine.

Below I have pasted the core stack

Hi

Have you tried a re-install of JDK, also did the first install show any errors?
