FULL OS VERSION :
Microsoft Windows 2000 [Version 5.00.2195]

A DESCRIPTION OF THE PROBLEM :
According to the API documents of above JDK versions, the static method java.sql.Timestamp.valueOf() should take only JDBC timestamp escape format which is yyyy-mm-dd hh:mm:ss.fffffffff. It throws an IllegalArgumentException if the given argument does not have the format yyyy-mm-dd hh:mm:ss.fffffffff.

In my test with the above versions, I used an invalid argument format "05-2003-02 0:0:0.0". The expected IllegalArgumentException was not thrown. Instead, the invalid argument was converted to a Timestamp with a String value equals "0171-11-02 00:00:00.0" under JDK version "1.4.1_01" and "171-11-02 00:00:00.0" under JDK version "1.3.1_06".



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile the source code provided below and run under either JDK version "1.4.1_01" or JDK version "1.3.1_06".


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
An IllegalArgumentException is expected to be thrown.
ACTUAL -
The invalid argument used was converted to a Timestamp with a String value equals "0171-11-02 00:00:00.0" under JDK version "1.4.1_01" and "171-11-02 00:00:00.0" under JDK version "1.3.1_06".


REPRODUCIBILITY :
This bug can be reproduced always.
