java.sql.SQLException: ORA-00600: internal error code, arguments error

Why am I getting this error while running the migrateDataToXml.sh script and how can I fix it?

Symptoms

When I run the migrateDataToXml.sh script, I get the following error:
java.sql.SQLException: ORA-00600: internal error code, arguments:  
[KGHALP1], [0x000000000], [], [], [], [], [], [], [], [], [], []

Causes

Oracle introduced certain performance improvements in the XML Parser of the 11 g release 2 version of the database. These improvement features also contain a defect, which is causing the preceding exception.

Resolving the problem

Work with your DBA to either install the Oracle patch fix or disable the feature, which contains this defect. You should either contact Oracle to get details about the patch or you can disable the feature with the following command:
alter system set event='31156 trace name context forever, level 0x400' scope=spfile;
IBM recommends installing the patch.
