****************************************************************
When Two CMPS have a CMR field with one-to-one
relationship, it's taking much longer to create the
second EJB and in a long run this can result in a
heavy performance hit. When the customer traced the SQL
flow, he was seeing an additional 'SELECT' statement
between INSERTS, where there should be only 2 INSERT
statements
Problem conclusion
ConcreteBeanStatefulInstanceExtensionImpl.java
class was modified. A check was made that if the
second EJB is newly created, no need to call
ejbLoad().
Temporary fix
A test fix is now available in
PQ99999. Please let the Customer
try it and provide feedback
