The method Statement.executeBatch does not work properly when an empty batch of statements is passed. For example, when Statement.addBatch is executed several times followed by a clearBatch and then execute Statement.executeBatch, executeBatch should return an integer array with 0 length. However, the bridge if presently returning a null instead of an integer array with 0 length.
