Resolution

The crash is happening in Java Native Access (JNA). JNA is used to access native libraries as an alternative to Java Native Interface(JNI) code.

JNA is not part of the Java JDK. The JNA library is distributed with the application and is therefore application code and not supported by Red Hat.

Next steps for troubleshooting should be from the JNA vendor. Red Hat will provide support for the underlying OpenJDK if the JNA vendor finds an issue with a valid/supported use case.

Root Cause

3rd party JNA library.

Diagnostic Steps

What is the application use case for JNA code?
