[infinispan-issues] [JBoss JIRA] (ISPN-10349) PersistenceManager.addSegments may never complete

PersistenceManager.addSegments may never complete ------------------------------------------------- Key: ISPN-10349 URL: https://issues.jboss.org/browse/ISPN-10349 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 10.0.0.Beta3 Reporter: Dan Berindei Assignee: Will Burns Priority: Major Labels: testsuite_stability Fix For: 10.0.0.Beta4 {{PersistenceManager.addSegments}} returns a {{CompletionStage}} which should be completed on a persistence executor thread. If the persistence executor was already stopped at the time {{addSegments()}} was called, however, the {{CompletionStage}} is never completed. This doesn't prevent the cache manager from stopping, but it causes a thread leak because a transport thread waits forever on the {{CompletionStage}}.
