I faced with that error message our 12c exadata system. Our development team send that error message to dba team.

Complete error message is:

[Error] Execution (1: 1): ORA-29548: Java system class reported: release of classes.bin in the database does not match that of the oracle executable
ORA-06512: at “MDSYS.SDO_JAVA_STP”, line 370
ORA-06512: at “MDSYS.SDO_UTIL”, line 3188
ORA-06512: at “MDSYS.SDO_UTIL”, line 321

I made some search and I found below select. If you try to run this query, you will hit same error as mention before.

SQL> select dbms_java.get_jdk_version() from dual
*
ERROR at line 1:
ORA-29548: Java system class reported: release of classes.bin in the database
does not match that of the oracle executable

So what is solution. You need to run /update_javavm_db.sql which is under javavm folder. After run below steps than please rerun select query again. You will see you will not hit this error message anymore.
