****************************************************************
The FinderCollectionIterator made use of an exhaustable
FinderEnumerator. Upon entry to the copyObject method, a
Tr.entry trace was cut, and that trace exhausted the
FinderEnumerator during the toString call on it. Upon exiting
the copyObject method, a Tr.exit trace was cut, and when the
toString method was driven, the exhausted FinderEnumerator
raised the NoSuchElementException.
Problem conclusion
The FinderCollectionIterator was modified to iterate over an
array of EJBObjects rather than using a FinderEnumerator. This
resolves the issue of the java.util.NoSuchElementException
being raised.
