javacore "gpf" on Cipher.doFinal

  • 1.  javacore "gpf" on Cipher.doFinal

    Posted Tue July 19, 2022 09:58 PM


    A piece of software from a vendor is failing when it tries to encrypt a file. I deploy the software as a WAR file into a WAS ND environment on RHEL 8.4. The javacore file indicates the problem is a "gpf", and the "sanitized" stack trace is shown below.

    Is there something I can do to WebSphere to prevent this error? Some parameter I can set?

    I appreciate any help or insight you can provide.

    I raised a ticket with IBM. They advised that in IBM/WebSphere/AppServer/java/8.0/jre/lib/security/java.security there is a "# List of providers and their preference" orders. In that list, it is important that IBMJCE be listed above IBMJCEPlus.

    This is the order I found:




    Based on IBM's comments, I switched IBMJCE and IBMJCEPlus. The above lines now look like this:




    I then tried to start the software, and it started without issue.
