Information in this document applies to any platform.
1. Oracle 11g Release 2 - 22.214.171.124 version, the following Internal Errors (ORA-600 & ORA-7445) occurs.
ORA-00600: internal error code, arguments: [ktcxbr0_1], [0x0B8102F40], , ,  ...
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;
Upgrade or Migration or Object re-validation.
