James F. Adams updated DERBY-1292:
----------------------------------
Attachment: DERBY-1292.diff
The attached patch contains the following:
1) The addition of a copy method to org.apache.derby.client.am.ColumnMetaData.
2) Modifications to org.apache.derby.client.am.PreparedStatement to hold on to
a copy of the column meta data for each entry used in batch updates.
3) A test was added to
org.apache.derbyTestingfunctionTests.tests.derbynet.prepStmt.
I ran derbynet/prepStmt as well as derbyall and did not see any new failures.
