Error in log after upgrade websphere from 18.104.22.168 to 22.214.171.124
We have Pega7.1.9 running on WAS126.96.36.199. We will update PRPC to 7.2.2. So we upgraded WAS to 188.8.131.52. After upgrading WAS while starting application with PRPC7.1.9 we are getting below error in log. Could you please help to resolve this.
Just to mention application is starting and we are able to login as well but seeing errors like below. Attached the full log.
