Potential concurrency issues when retrieving a cache concurrently (for the first time) -------------------------------------------------------------------------------------- Key: ISPN-1051 URL: https://issues.jboss.org/browse/ISPN-1051 Project: Infinispan Issue Type: Bug Components: Core API Affects Versions: 4.2.1.FINAL Reporter: Emmanuel Bernard Assignee: Dan Berindei Priority: Critical Fix For: 4.2.2.BETA1 My code initialize the CacheManager but retrieve the cache only "on demand". Several threads do access cacheManager.getCache(namedCache); concurrently. I am experiencing the following exceptions {code}Caused by: org.infinispan.config.ConfigurationException: Component factory class org.infinispan.factories.EmptyConstructorFactory incorrectly registered!
