[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-5866) ServiceRegistry is not thread-safe

ServiceRegistry is not thread-safe ---------------------------------- Key: HHH-5866 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5866 Project: Hibernate Core Issue Type: Bug Components: core Reporter: Emmanuel Bernard Fix For: 4.0.0.Alpha1 ServiceRegistryImpl uses a HashMap which is not thread-safe. Services can be initialized lazily which means several threads can end up asking for the same service in // The implementation needs to guard against that. note that using a ConcurrentHashMap is not good enough as we probably don't want the same service type to be initialized multiple times.
