Actually this behavior is correct according to the JDBC spec. If you see
Appendix B [1] it says:
Note - The JDBC 1.0 specification defined the Java object mapping for the
SMALLINT and TINYINT JDBC types to be Integer. The Java language did not
include the Byte and Short data types when the JDBC 1.0 specification was
finalized. The mapping of SMALLINT and TINYINT to Integer is maintained
to preserve backwards compatibility.
