This was produced using a UnitTest that simply creates a prepared statement similar to:

preparedSql = "UPDATE vm1.g1 SET vm1.g1.e2=? WHERE vm1.g1.e1=?"
values.add(new ArrayList<Object>(Arrays.asList(new Object[] { new Integer(0), "a" })));
values.add(new ArrayList<Object>(Arrays.asList(new Object[] { new Integer(1), "b" })));

Then execute the prepared statement.  

Attached unit test patch includes the failing unit tests against a virtual and some refactoring of the existing unit test methods to handle some unit test framework changes from R050503.
