Teiid does not return genereted keys after executeBatch

Currently, Teiid does not return genereted keys after inserting value using PreparedStatement.executeBatch() method. JDBC (4.1) does not require this :

It is implementation-defined as to whether getGeneratedKeys will return generated values after invoking the executeBatch method.

However, it would be nice to have this behavior documented - https://teiid.gitbooks.io/documents/content/client-dev/JDBC_Support.html
