Applies to:

Oracle Server - Enterprise Edition - Version 11.2.0.3 and later
Information in this document applies to any platform.

Symptoms

1. Oracle 11g Release 2 - 11.2.0.3 version, the following Internal Errors (ORA-600 & ORA-7445) occurs.

ORA-00600: internal error code, arguments: [ktcxbr0_1], [0x0B8102F40], [7683], [2097152], [] ...

The above errors are not necessarily due to stray Java objects like 'prv//////KGLNECFEAAAAAAAA' but due to internal corruption. 

2. Objects in the form of "prv//////FOHFBEJIAAAAAAAA" is not a "JAVA CLASS" but rather "JAVA DATA" object_type.  Normally such objects are similar to 'prv//////KGLNECFEAAAAAAAA'.  

Seems to start with 'prv/////' and end with 'AAAAAA'. 

3. It looks like DDL operations are being performed, the SQL statement from the trace when the error occurs shows:

ALTER JAVA CLASS "SYS"."prv//////HJIOLPOAAAAAAAAA" CHECK;

Changes

Upgrade or Migration or Object re-validation.
