Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server Liberty - Java Persistence API (JPA  *
*                  2.1) using DB2                              *
****************************************************************
* PROBLEM DESCRIPTION: Setting javax.persistence.lock.timeout  *
*                      to 0 causes EclipseLink JPA 2.1         *
*                      provider to throw a                     *

* RECOMMENDATION:                                              *
****************************************************************
Setting the property to 0 caused EclipseLink to add a NOWAIT to
the SQL. DB2 does not support NOWAIT and therefore throws an
exception.
