      Use the attached byteman script

      JAVA_OPTS=-javaagent:$BYTEMAN_HOME/lib/byteman.jar=script:/path/to/pauseHAJNDIinit.btm

      (This script just pauses at the right spot to make it easier to trigger the bug.
      Without the script, just restart JBoss repeatedly while hitting HA-JNDI until the
      timing is just right to trigger it).

      From a standalone client configured with jndi.properties to hit HA-JNDI, run:
      new InitialContext().lookup ( "foo" );

      In some circumstances, HA-JNDI could start processing requests before it was fully initialized, causing those requests to fail with a NullPointerException. This has now been resolved so that initialization is confirmed before processing begins.

      HAJNDI starts processing requests before it has fully initialized itself.
      This can cause those requests to fail with:

      java.lang.NullPointerException
