FULL PRODUCT VERSION :
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
If JdbcRowSetImpl.setAutoCommit() is called before calling JdbcRowSetImpl.execute() it raises a NullPointerException.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run the attached program.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
I would expect no exception because it is stated in the doc RowSet are beans like API allowing to configure a connection to a database to retrieve rows. So I except to be able to set all the flags before calling the execute method.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Exception in thread "main" java.lang.NullPointerException
at com.sun.rowset.JdbcRowSetImpl.setAutoCommit(JdbcRowSetImpl.java:4042)
at ilog.views.util.data.RowSetPb3.test(RowSetPb3.java:43)
at ilog.views.util.data.RowSetPb3.main(RowSetPb3.java:29)

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
call setAutoCommit after execute.
