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

             Summary: Test cache managers created in other threads cannot join the UDP cluster
                 Key: ISPN-10080
                 URL: https://issues.jboss.org/browse/ISPN-10080
             Project: Infinispan
          Issue Type: Bug
          Components: Test Suite - Core
    Affects Versions: 9.4.11.Final, 10.0.0.Beta3
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 10.0.0.Beta4, 9.4.12.Final


When a test wants to create a cache manager in another thread (e.g. with {{fork()}}) it should be able to call {{TestResourceTracker.testThreadStarted(this)}} and join the same cluster.

That works with TCP, but with UDP each thread gets its own multicast address and port, so multicast messages from one node don't reach the other. Unicast messages and {{TEST_PING}} do work.

This is the issue that made {{FunctionalTxTest}} fail in https://github.com/infinispan/infinispan/pull/6442
