Error description

• When trying to access a CMP entity bean using the
  findbyprimarykey, the following exception is thrown:
  ----------------------------------------------------------------
  javax.ejb.TransactionRolledbackLocalException: ; nested
  exception is: java.lang.ArrayIndexOutOfBoundsException: 0

  at com.ibm.ws.ejbpersistence.dataaccess.ResultCollectionImpl.
  processSingleRow(Unknown Source)
  ----------------------------------------------------------------
  
  The problem was found to be within the EJBdeploy code generation
  tool.  This needs to be fixed in AST v6.0, AST v6.1, WAS v6.0,
  and WAS v6.1.

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of CMP EJBs running on WebSphere   *
  *                 Application Server that make use of          *
  *                 read-ahead access intents.                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: The inclusion of read-ahead access      *
  *                      intents on CMP EJBs may cause           *
  *                      ArrayIndexOutOfBoundsExceptions         *
  *                      during runtime.                         *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  The inclusion of read-ahead access intents on CMP EJBs
  involved in multiple relationships will cause the EJB Deploy
  code generation tool to produce symantically incorrect source
  code that can result in an ArrayIndexOutOfBoundsException when
  accessing the extractPrimaryKey() method of the
  application-specific BeanExtractor class.
  

Problem conclusion

• The logic for parsing the JDBC indexes for the columns that
  are included in the read-ahead access intent has been improved
  to properly handle multiple CMP relationships.
  The fix for this APAR is scheduled for inclusion in the
  WebSphere Application Server v6.0.2.29 and v6.1.0.19 fix packs.
