Issue with Oracle.sql.NUMBER in Java Stored Procedure

Question

When we try to make a call to the Oracle.sql.NUMBER(String) inside a java stored procedure and pass values from '01' to '09', it throws java.lang.StringIndexOutOfBoundsException: String index out of range: 3
We use Oracle 9.2.0.6 - JServer Release 9.2.0.6.0.
It works fine for other values. Please find below the code used for simulating the issue outside the application. Thanks.
create or replace and compile java source named testNumber as
import oracle.sql.NUMBER;
import java.sql.SQLException;
public class TestNumber
       public static String convertNumber(String parm) {
                 NUMBER nTest;
                 try {
                         nTest = new NUMBER(parm);
                         return "TRUE";
                 }catch (SQLException sqle) {
                         return "FALSE";
create or replace function test_number (p_str in varchar2) return varchar2 as
language Java name 'TestNumber.convertNumber(java.lang.String) return
java.lang.String';
select test_number('05') from dual;  - Throws exception ORA-29532: Java call terminated by uncaught Java exception: java.lang.StringIndexOutOfBoundsException: String index out of range: 3
select test_number('5') from dual; - Works fine
select test_number('010') from dual; - Works fine

Siva,
I'm only guessing, but it could be an Oracle bug, in which case I suggest checking with Oracle Support.
(You do have a support contract, don't you? ;-)
Did you try compiling and running your java class "TestNumber" outside the database?
Class "oracle.sql.NUMBER" should be in Oracle's JDBC driver, I believe.
Good Luck,
Avi.
