  The problem symptom is an error message containing error codes
  "DSRA8040I" and "JVMCFRE199E". For example:
  DSRA8040I: Failed to connect to the DataSource "". Encountered
  java.lang.UnsupportedClassVersionError: JVMCFRE199E bad major
  version 55.0 of class=jakarta/json/JsonValue, the maximum
  supported major version is 52.0; offset=6
  This connection failure causes failures of applications which
  rely on the Oracle JDBC driver.
  The root cause of the failure is a failure to load class
  "jakarta.json.JsonValue", which is attempted by the the Oracle
  (TM) JDBC driver JAR file version 8, "ojdbc8.jar".
  The class load is attempted because the class is visible on the
  server runtime class path, because of the addition of JAR file
  "lib/jakartaee10.jar" to WebSphere Application Server
  v9.0.5.23.
  The new JAR is used when performing MoRE deployments and is
  used
  to scan when scanning application classes. The problem is that
  the new JAR file is implicitly visible on the server runtime
  class path.
  .
  Additional Symptoms:
  .
  Message CNTR0020E: EJB threw an unexpected (non-declared)
  exception during invocation of method "some-method-name"
  on bean "some-bean-id-name".
  .
  Exception data: java.lang.UnsupportedClassVersionError:
  JVMCFRE199E bad major version 55.0 of
  class=jakarta/ws/rs/core/Response$Status,
  the maximum supported major version is 52.0; offset=6
  

Problem conclusion

• This APAR was fixed by moving "jakartaee10.jar" to a sub-
  directory of "lib".  The subdirectory is not implicitly on the
  application server's class path.  MoRE specific application
  deployment code was updated to use "jakartaee10.jar" at the new
  location.
  
  This APAR is specific to users of version 8 of the Oracle JDBC
  driver JAR file.  Users of other version of the Oracle driver
  JAR file should not encounter this APAR.
  
  Fix available here:
  https://www.ibm.com/support/pages/node/7230504
  
  
  The fix for this APAR is targeted for inclusion in fix pack
  9.0.5.24. For more information, see 'Recommended Updates for
  WebSphere Application Server':
  https://www.ibm.com/support/pages/node/715553
  

Temporary fix

• Unless MoRE application deployments are being performed, the
  problem may be safely circumvented by removing the
  "lib/jakartaee10.jar" JAR file from the WebSphere installation.
