java.lang.RuntimeException: Problem during method invocation (contextInitialized)
Caused by: java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=com/pega/pegarules/internal/bootstrap/phase2/PRBootstrapImpl, offset=6

Steps to Reproduce

  1. Deploy copy of Pega 7.1.8 application via impdp.
  2. Set up WebSphere environment.
  3. Configure
  4. Launch Update_Setup.jar from Windows PC.
  5. Set up DB (Oracle) connection parameters.
  6. Start upgrade.
  7. Wait for Upgrade to finish.
  8. Check PRPC_Setup.log.
  9. Delete WAS temp dirs and PegaRULES_Extract_Marker.txt.
  10. Start WAS server.
  11. Check WAS server's SystemOut.log.

Root Cause

Incorrect JVM version.


The Websphere environment is configured to use Java 1.6 which is causing the issue as one can see in the systemout.log that is provided in the java version is 1.6

Also start up is showing the same information

Upgrading the Websphere JRE resolved the JVMCFRE003 incorrect major version; class=com/pega/pegarules/internal/bootstrap/phase2/PRBootstrapImpl, offset=6 that was occurring during startup.
