Add “window” of different NULL sorting behavior to DBMD.nullsAreSortedAtStart (4.0.2 to 4.0.10, true; otherwise, no).

Implemented Blob.setBytes(). You still need to pass the resultant Blob back into an updatable ResultSet or PreparedStatement to persist the changes, because MySQL does not support “locators”.

More checks added in ResultSet traversal method to catch when in closed state.

Fixed ResultSetMetaData.isWritable() to return correct value.

Clean up Statement query/method mismatch tests (that is, INSERT not permitted with .executeQuery()).

Allow ignoring of warning for “non transactional tables” during rollback (compliance/usability) by setting ignoreNonTxTables property to true.

Fixed ResultSetMetaData to return "" when catalog not known. Fixes NullPointerExceptions with Sun's CachedRowSet.

Fixed SQLExceptions getting swallowed on initial connect.

Fixed DBMD.getTypeInfo() and DBMD.getColumns() returning different value for precision in TEXT and BLOB types.

Fixed Statement.setMaxRows() to stop sending LIMIT type queries when not needed (performance).

Backported 4.1 charset field info changes from Connector/J 3.1.
