Red Hat Single Sign-On (RH SSO) 7.5.0 GA hangs or outputs the error message "Error loading module from /opt/eap/modules/system/layers/base/org/aesh/main/module.xml" during the boot process

Issue

• The RH SSO 7.5.0 GA container gets killed after around ~3 minutes and produces no further messages. When looking at the logs, it freezes in the following:

  WARN Detected missing JGroups encryption configuration, the communication within the cluster WILL NOT be encrypted.
  

• When testing migration to RH-SSO 7.5.0 GA we observed the the application would not start and the following error message is displayed:
