Below is the root cause of the regression - javax.security.auth.Subject.getSubject() throwing UnsupportedOperationException if -Djava.security.manager=allowed isn't configured in Artemis server environment.
This regression was introduced with this JDK commit

Failure in initialisation: java.lang.UnsupportedOperationException: getSubject is supported only if a security manager is allowed
