Customer reported that after applying latest WebLogic security patches (PSUs) on WebLogic 12.1.3 installation they started getting Coherence cache (session) data (de)serialization errors in certain situations. They have seen the same issue with the latest version of WebLogic Server 188.8.131.52.0. Later they have rolled back the critical security patches but that is only temporary fix.
