To make it work again one have to "dump" the shared archive file again.

A jar file is not the one used while building the shared archive file. Error occurred during initialization of VM Unable to use shared archive. REPRODUCIBILITY : This bug can be reproduced always. CUSTOMER SUBMITTED WORKAROUND : Rebuild the shared archive file twice a year manually is NOT an option for JOE the user rendering CDS useless.
