-------------------------------------------------------------------

[~honza889] Sure, that would be better, particularly if it is easy to set up and avoids conflicts with random other stuff that may be on the machine. Note that it's different ports per test method not just per test class. The failures are usually within the same class.

Also, I thought about looping through a set of expected-to-be ok ports (rather than just blindly incrementing and hoping you don't hit a conflict) but a caveat is I've observed that just a 50 ms sleep still produced failures. 100 ms seemed ok, at least on ci.wildfly.org. So any set of "ok ports" would have to be big enough to allow enough tests to run and time to pass before starting over.

> Following combination of tests will fail *sometimes* on "Address already in use: bind" on windows:
> {code}
> mvn test -Dtest=org.jboss.as.controller.test.RemoteChannelProxyControllerTestCase,org.jboss.as.controller.test.TransactionalProtocolClientTestCase
> {code}
> {code}
> [Step 2/3] org.jboss.as.controller.test.TransactionalProtocolClientTestCase
> [21:41:55][org.jboss.as.controller.test.TransactionalProtocolClientTestCase] testSequentialGroup
> [21:41:55][org.jboss.as.controller.test.TransactionalProtocolClientTestCase] testCancelBeforePrepared
> [21:41:55][testCancelBeforePrepared] java.net.BindException: Address already in use: bind
> [21:41:55]

> This happens pretty often on windows CI:
> https://ci.wildfly.org/project.html?projectId=WildFlyCore_PullRequest&testNameId=-1770791349410974648&tab=testDetails
> But it is sufficient to run combination of tests above on Windows to reproduce.
