> DATE column is nullable in db schema, so it should pass there ok. I believe the problem
is in org.apache.derby.iapi.types.SQLDate, which does not implement setInto method, so DataType.setInto
method is executed, calling setObject(x,null). setObject thinks this is JDBC spec violation
and fails on exception.
> Problem exists in both 10.0.2.1 and 10.0.2.0
