New Management Jars do not work on previous app-server versions

I'm not sure if this is in the correct component, however, using the new management jars in JBoss 7.1 beta1, and trying to access the management functions of as7.0.x, the result is not successful. These jars need to be tested for regressions with previous versions.

My first test against what seems to be 7.0.0.final (built 5 days before the release, so I suspect it was a near-final build) involved the following error in the CLIENT:

Caused by: javax.security.sasl.SaslException: No more authentication mechanisms to try

A try against 7.0.2 has different results: when the server started up, the test client simply freezes, with the following stack trace:

Object.wait(long) line: not available [native method]
ManagementRequest$ManagementFuture<T>(Object).wait() line: 485
ManagementRequest$ManagementFuture<T>(AsyncFutureTask<T>).await() line: 192

No result is ever found.

The exception on the server when performing this test client is as follows:

17:55:57,187 ERROR [org.xnio.listener] (XNIO NIO Read 1) A channel event listener threw an exception: java.lang.IllegalStateException: Unsupported Callback 'ANONYMOUSanonymous'

The test client's logic will be attached momentarily
