WebLogic 15.1.1 T3/JNDI Thin Client Regression

in Oracle Weblogic Server (MOSC) 2 commentsAnswered

We hit two different problems while moving from wlthint3client-14.1.2 to wlthint3client-15.1.1 on JDK 17:

  1. A startup classloading issue in JNDI (org.omg.CORBA.SystemException missing).
  2. After fixing that, a deeper WL15 T3 bootstrap timeout (ConnectionManager.bootstrap wait -> timeout).

The first one is understood and has a workaround. The second one is the real unresolved defect.

Problem 1: JNDI fails without CORBA classes (workaround available)

What it looks like

When the client runs with wlthint3client-15.1.1.jar on JDK 17 and no extra CORBA API, it dies very early:

java.lang.NoClassDefFoundError: org/omg/CORBA/SystemException  at weblogic.jndi.WLInitialContextFactoryDelegate.<clinit>(WLInitialContextFactoryDelegate.java:202)Caused by: java.lang.ClassNotFoundException: org.omg.CORBA.SystemException
