-------------------------------------
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.
Example stack trace from the wildfly-maven-plugin:
