The problem seems to have changed since I added -Xcheck:jni.

There is no hs_err file produced but there is a hugh 400mb+ core file and this in the log:

     [java] FATAL ERROR in native method: Null object passed to JNI

How should I make the core file available to you?

The JVM crashes while running jvoicebridge java application.
This is an intermittent problem but seems to happen about once a day.

The application has no native code.

I've attached two different error reports.
