A new OC4J instance is created and started with the java option -Djava.ext.dirs=<jdbc 10204> where <jdbc 10204> is a directory containing the jdbc jar file ojdbc14.jar

After restarting this new OC4J instance, the ASC console is not accessible: it hangs on the login screen.

The following error is shown in the ASC console log file.
