[infinispan-issues] [JBoss JIRA] (ISPN-10080) Test cache managers created in other threads cannot join the UDP cluster

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: 10.0.0.Beta3, 9.4.11.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major 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
