EJB Calls Stopped Working After Migration To Java 11

in Oracle Weblogic Server (MOSC) 1 commentAnswered

My company has several different applications running as J2EE, on Weblogic servers.

Several of these apps interact between themselves using EJB calls.

We recently migrated two of those applications from Java 8 to Java 11 and although they are working fine on their own, the EJB calls between them stopped working and we get the error I'm attaching here.


We have spent several hours trying to fix this, mostly analyzing third-party dependencies for both apps, but we couldn't progress at all.
