Abstract:  jndi failure after upgrading websphere application server to 9.0.5.10

Description/symptom of problem:  
PH43816 resolves the following problem:

ERROR DESCRIPTION:
JNDI operation may fail due to an Exception while attempting    
to obtain an object instance from an ObjectFactory. In          
previous releases such an Exception was caught and alternative  
methods of retreiving the object instance were performed        
successfully.

LOCAL FIX:
                                                                

PROBLEM SUMMARY:

USERS AFFECTED:
 All users of IBM WebSphere Application
Server

PROBLEM DESCRIPTION:
JNDI operations fail if an
ObjectFactory throws an Exception.

RECOMMENDATION:
None

The fix for APAR PH02744 backported, into WebSphere Application
Server, the fix for an issue in the open source Apache Aries
project identified in JIRA ARIES-1068.
When obtaining an object instance, the OSGi JNDI
implementation's InitialContextFactoryBuilder must try several
different methods to obtain the instance.  The fix modified the
Exception handling such that an Exception from one such method
was no longer handled causing a premature failure of the
attempt.

PROBLEM CONCLUSION:
The defect in Apache Aries JIRA ARIES-1068 was identified and   
fixed in Apache Aries JIRA ARIES-2000.  The fix for this APAR   
backports the open source fix for the ARIES-2000 JIRA into the  
version of Apache Aries shipped in WebSphere Application Server.
                                                                
The fix for this APAR is targeted for inclusion in fix pack     
9.0.5.11. For more information, see 'Recommended Updates for    
WebSphere Application Server':
