Locally the feature is refused during a call to getMBeanServerConnection(with a non-null delegationSubject). Remotely, `javax.management.remote.rmi.RMIConnectionImpl` has methods which accept a Subject parameter for Subject Delegation. This cannot now be non-null in local usage, but an RMI Connection from an older JDK can invoke these methods with a non-null delegationSubject. Such access will be recognised and an UnsupportedOperationException will be thrown (which the client will see). RMIConnectionImpl can be simplified, and the class SubjectDelegator removed. JMXSubjectDomainCombiner I would like to remove separately after this is done. ------------- PR Comment: https://git.openjdk.org/jdk/pull/18025#issuecomment-1972845693
