1. Bouncy Castle library

• WebLogic 12c is distributed with bcprov-jdk16-1.45.jar, but Magnolia is distributed with bcprov-jdk16-1.46.jar
• Symptoms:
  • M4.5.x - There is no error shown on "Magnolia license" form, but license is not registered. And in log there is this stack trace

    SEVERE: Can't read license for module enterprise

  • M5.2.x - after insterting valid license key into "Magnolia license" form. Error message "License is empty." appears on.
• Solution:
  • Edit setDomainEnv.sh in WebLogic and add bcprov-jdk16-1.46.jar to PRE_CLASSPATH.
  • Remove bcprov-jdk16-1.45.jar from WebLogic 12c common libraries

2. Magnolia Workflow with JBPM 6

• Deploying Magnolia with JBPM 6 affects deployment feature of Weblogic AS. It does't care if Administration Console, weblogic.Deployer, wldeploy Ant task or auto deploy directory is used all are affected.
• Symptoms:
  • Magnolia can't be deployed to Weblogic. "weblogic.application.ModuleException: java.lang.ClassNotFoundException: org.jbpm.services.task.lifecycle.listeners.TaskLifeCycleEventListener". Full stacktrace http://pastebin.com/gsUy28DU
• Workaround:
  • First deploy application which doesn't contain Magnolia Workflow with jbpm6 (etc. M5.2.2, M5.3 without workflow, etc.). And then in deployment target location replace deployed webapp by new webapp which contains workflow with jbpm6
• We are still analyzing the problem and looking for better solution
