Wondering if you had look into this. As Myrna sadi, since you wrote these tests I want you to review this before going ahead.

---------------------------------------
I have attached the changes I did to parameterMapping.java and the output I got. It is slightly tricky to figure out the failures when they occur for certain datatypes with the setNull method with batching turned on.
Firstly, I want to confirm the addition I did to the test is fine. If the additions are fine then I can start to figuring out which tests failed ( with batching turned on ) but are supposed to pass. The only way I found was comparing the output, the addition to the test case produces with the output got when batching is not performed, i.e comparing the output of executeUpdate() with executeBatch().
A peek into the output file I have attached will give a clearer picture of what I am trying to say. Correct me if I am wrong or suggest a better way to detect failures than what I am doing.
setNull(x,JDBCType.DATE) does not work when batching is turned on -----------------------------------------------------------------

Trying to execute batch on which setNull(x,DATE) was called gives the following exception:
SQL Exception: An attempt was made to get a data value of type 'DATE' from a data value of type 'null'.

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
