The issue is related to Sun’s JDK bug when using JDK 1.5 with IPv6 enabled. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6206527
To implement the solution,
- Set the command line option -Djava.net.preferIPv4Stack=true in the oc4j java-options for both start and stop categories.
- Restart the server. After restart you should not be seeing these error any more.
