Why I always get the error(ORA-00600)?

Question

Why I always get the error(ORA-00600)?
My database Oracle 9.2.0.1.0 I installed Oracle Jdeveloper 9i on my computer.
OS:windows2000
My program:
Class.forName("oracle.jdbc.driver.OracleDriver");
con =java.sql.DriverManager.getConnection("jdbc:oracle:thin:@server:1521:db","developer","12345");
java.sql.Statement stmt=con.createStatement();
java.sql.ResultSet rs=stmt.executeQuery("select task_title from task");
while (rs.next()){              
     //getInformation
     String fjbh=rs.getString("task_title");
If I use this in a common java program(like MyParser.java). It will work well:
D:\JavaApp> java MyParser
but If I put the code into a JSP file . It will not work.I tried several times.
I find that the statment:
     java.sql.ResultSet rs=stmt.executeQuery("select task_title from task");
will throw the exception.It seemd that I can connect to the database ,
but can not execute some sql statment.
If I execute this sql statment:
     select sysdate from dual ;
     or
     select task_ID from task ; --task_id is a column with the type NUMBER(10)
it will work.
but if I execute :
     select Task_Title from task where task_id=1; --Task_Title is a column with the type VARCHAR(50)
     or
     select t.task_text.getCLOBVal() task_Text from task t where task_ID=1;
               --task_text is a column with the type XMLTYPE, I use this column save XMLFile.
it will not work.
the detail error information as follow:
java.sql.SQLException: ORA-00600: internal error code, arguments: [ttcgcshnd-1], [0], [], []

It is a database bug (an ORA-0600 almost always is). In this case it is bug# 1725012. You can see the details from MetaLink. There are some patches (by platform) available you should see which may apply to you.
