Can't update clob with foreign characters using UPDATEXML in Java

问题

I am trying to update Georgian characters into a clob that is used for XML. I had to use clob, since the text is usually quite large. this is my update part:

select = "update datadocumentxml d\n" +
                "   set d.datadocumentxml = updatexml(xmltype(d.datadocumentxml),'/Comments/@Comment', ?)\n" + 
                "                                   .getClobVal(),\n" + 

                " where d.processengineguid = fnguidjava2raw(?)\n" + 
                "   and d.datadocumentid = 'Comments'";
    ps = conn.prepareStatement(select);

    ps.setClob(1,clob);
    ps.setString(2,processid);
    rs = ps.executeQuery();

this code works perfectly on English, Russian, Arabic and some characters. But when I try to update Georgian letters that are like 6+ characters, I get internal errors. I also tried Japanese letters and they don't work either.

this is the error:

Caused by: java.sql.SQLException: ORA-00600: internal error code, 
arguments: [17114], [0x7FEA96179698], [], [], [], [], [], [], [], [], [], []

I think it has something to do with JDBC drivers and charsets..

any suggestion would be greatly helpful. thanks.
