James Perkins created WFCORE-2705: ------------------------------------- Summary: The default ModelControllerClient closes resources asynchronously could cause intermittent issues in consumers Key: WFCORE-2705 URL: https://issues.jboss.org/browse/WFCORE-2705 Project: WildFly Core Issue Type: Bug Components: Domain Management Reporter: James Perkins Assignee: James Perkins The {{RemotingModelControllerClient}} closes some of it's resources asynchronously. This could cause issues consumers of the client that may attempt to change class loaders after the client is closed. The {{ModelControllerClient.close()}} should block until resources are closed.
