Hi, I have a field which type is TINYINT(1), and when I use "ResultSet.getByte()" to get the value, I encounter an exception:
java.lang.ClassCastException: java.lang.Short
at com.mysql.jdbc.ResultSet.getNativeByte(ResultSet.java:4172)
at com.mysql.jdbc.ResultSet.getByte(ResultSet.java:729)
at com.mysql.jdbc.ResultSet.getByte(ResultSet.java:742)
at org.apache.tomcat.dbcp.dbcp.DelegatingResultSet.getByte(DelegatingResultSet.java:230)
at org.tangniaobing.database.UserDB.BindDataToUser(UserDB.java:369)
......

Environment:
-------------------------------
MySQL: 4.1.8 nt
Connector-J: 3.1.6
WebServer: Tomcat 5.5.4
JDK: Sun JDK 5.0 Update 1 (1.5.0_01)

+---------------------+-----------------------+------+-----+---------------------+----------------+
| Field | Type | Null | Key | Default | Extra |
+---------------------+-----------------------+------+-----+---------------------+----------------+
| Gender | tinyint(1) unsigned | | | 0 | |
+---------------------+-----------------------+------+-----+---------------------+----------------+

-------------------------------


by the way:
When I use Connector-J 3.0.16 & J2SDK1.4.2_06 & Tomat 5.0.30, these code runs OK.

Is it a BUG or what ?
