SearchFactoryState should use concurrent Maps for incrementally updated metadata -------------------------------------------------------------------------------- Key: HSEARCH-822 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-822 Project: Hibernate Search Issue Type: Bug Components: engine Affects Versions: 3.4.0.Final Reporter: Sanne Grinovero Assignee: Sanne Grinovero Fix For: 4.0.0.Alpha1 I've experienced very sporadic failures of MutableFactoryTest, when trying again it won't be reproduced. The Workspace goes in NPE on the single-line method {code}org.hibernate.search.backend.Workspace.getDocumentBuilder(Class<T>){code} So it seems it's receiving work for a new entity type while the document builder of it was not "deployed" yet. Indeed these DocumentBuilders are stored in a non-concurrent HashMap, replacing the implementation with a CHM it's now running the tests in a loop without reporting the exception anymore. -- This message is automatically generated by JIRA.
