APAR status
Closed as program error.
Error description
As part of Java batch runtime processing, it will use the admin client to get configuration information. This will make a SOAP call using SSL to the control region. If the SSL handshake fails, you will see these NullPointerExceptions: java.lang.NullPointerException at com.ibm.ws.gridcontainer.config.ConfigurationUtility.getEBA List(ConfigurationUtility.java:406) java.lang.NullPointerException at com.ibm.ws.gridcontainer.config.ConfigurationEventsListener .registerApplicationMBeanListener(ConfigurationEventsListener.j ava:394) java.lang.NullPointerException at com.ibm.ws.gridcontainer.config.ConfigurationEventsListener .registerEBAMBeanListener(ConfigurationEventsListener.java:363)
Local fix
Fix the SSL handshake error. If using client authentication, ensure the servant region keyring contains a personal certificate.

This exception by itself isn't particularly helpful in indicating or determining the root cause of the problem. For the reported problem case, the root cause was that the z/OS servant keyring did not have a personal certificate and the Client authentication property was set to "Required". When the control or servant region makes an outbound SOAP call to the same servers SOAP port the server asks the client for a personal certificate for client authentication.
Problem conclusion
A new message was created and a code update was made to better record that this problem has occurred, and to better indicate wh should be investigated to resolve it. The fix for this APAR is targeted for inclusion in fix pack 9.0.5.17 and 8.5.5.24.
