Opatch error "Exception in thread "main" java.lang.UnsupportedClassVersionError"

Hello,

I'm upgrading Oracle to 12.1 and I'm blocked with Opatch step.

I replaced Opatch by the last version for 12.1 but I continue to get an error when à try to use it. Command like "opatch version" give that :

E:\oracle\SID\12102\OPatch>opatch version
========================================================
GENERIC OPATCH VERSION - FOR USE IN SAP ENVIRONMENT ONLY
========================================================
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

OPatch failed with error code = 1

Is someone has an idea of what's wrong ?

Thanks !

    OK, stupid error ... and solution ... Variable ORACLE_HOME changed to the NEW_ORACLE_HOME but session not restated.
