Currently, when we embed the SimplePush server in WildFly we use the Netty subsystem. The idea behind this was that it would be a generic subsystem and usable by others.
This has not worked out that well and more and more issues have cropped, plus the advice from the WildFly team is to create a specific subsystem for our specific need.
This JIRA should create a subsystem specific for our SimplePush server.
