Temporary fix
Comments
This APAR adds support to CICS so you can, if you choose, specify a new WLP_INSTALL_DIR value in your JVM profile to use an alternative version of Liberty from the one that is supplied with CICS. The CICS Knowledge Center will be updated to document that the JVMSERVER JVM profile option WLP_INSTALL_DIR can now be used to specify the installation directory of an alternative Liberty version. In such cases CICS will verify the level of Liberty by: - Enforcing a minimum version of Liberty. If you attempt to launch a version of Liberty below the minimum level supported by CICS, an exception is thrown and the Liberty JVM server does not start. The exception message - written to JVMLOG and STDERR - indicates the version of Liberty being launched and the minimum version accepted. - Issuing a warning if the version of Liberty being launched is greater than the maximum version of Liberty supported by CICS. The warning is written to JVMLOG and Liberty continues to launch. This might happen if CICS has not yet offered official support for this level of Liberty, or if you have not applied the companion CICS service APAR. If this is encountered, it is prudent to confine your use of such versions to test, prototype or development systems. The minimum and maximum supported Liberty versions will be reassessed regularly and changed when appropriate by the quarterly CICS Liberty fixpack APAR. At present this functionality supports Liberty 20.0.0.9 following the closure of APAR PH28793.
