Hi, We have what we believe to be working AS - undertow integration ready! You can see it at https://github.com/undertow-io/jboss-as I have just merged in https://github.com/undertow-io/undertow-subsystem repo. That means two things, undertow-subsystem repo won't be in use anymore. All subsystem/integration related development should go against that repo or jboss-as upstream directly once we have it merged to upstream. I will prepare PR for merging to upstream master tomorrow so we can get some proper reviewing done before it is merged. p.s. to build it you need to take also https://github.com/undertow-io/undertow/pull/62 at least until it is merged to undertow. -- tomaz
