    The problem you are seeing might be related to the the Java/JDK version that is being used with UCD. We are currently investigating issues with the Java IBM 1.8.0_281, please create a case requesting assistance from support since we need to do a deeper investigation on this issue.

    We've identified the problem is caused by zOS <JAVA_HOME>/lib/security/java.security file missing the IBMJCEPlus provider.

    Compare to another zOS LPAR which has the IBMJCEPlus provider, that one is working fine.

    Our zOS Java is 1.8.0_291 SR6_FP31
