APAR status
Closed as program error.

Error description
IBMer has identified a problem in the WebSphere Orb
(iwsorb.jar) for version 4.0.2 and beyond.
The following ArrayIndexOutOfBoundsException occurs
intermittenly.  This problem occurs when WebSphere is
communicating with a Java application using CORBA, and the
Java Application is using Java 1.4.
Local fix
Suggested fix is to update the ObjectKey.getServerUUID()
function:

****************************************************************
In a typical topology, WebSphere is acting as a client, which
uses IBM ORB to communicates with other non IBM ORB vendor
(could be Java or C++). When WebSphere ORB receives an Object
Key generated from the non IBM ORB, it examines both of its
size and content. If the Object key is shorter than it expects
(16 bytes), WebSphere ORB would throw the following
exception.

java.lang.ArrayIndexOutOfBoundsException
at java.lang.System.arraycopy
 (Native Method)
at com.ibm.CORBA.iiop.ObjectKey.getServerUUID
 (ObjectKey.java:117)

(IpMultiPartyCallControlManagerHelper.java:73)
Problem conclusion
When WebSphere ORB finds the Object Key is shorter than 16
bytes, it will fill up the remaining bytes with the value of
zeros and maintain all Object Keys, generated by either IBM ORB
or non IBM ORB, as 16 bytes long.
