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.
