NPE in SearchFactory while using different threads -------------------------------------------------- Key: HSEARCH-21 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-21 Project: Hibernate Search Type: Bug Components: engine Reporter: Sylvain Vieujot java.lang.NullPointerException at org.hibernate.search.SearchFactory.getSearchFactory(SearchFactory.java:120) at com.seanergie.persistence.SessionsManager.getSearchFactory(SessionsManager.java:374) ... The contexts ThreadLocal is missing a get method. it is initialized by the first thread that uses it by the static statement, but for the next Thread it hasn't been initialized, and so it contexts.get() returns null. Simple fix : add the get method as follows : public class SearchFactory { private static ThreadLocal<WeakHashMap<Configuration, SearchFactory>> contexts = new ThreadLocal<WeakHashMap<Configuration, SearchFactory>>(){ @Override public WeakHashMap<Configuration,SearchFactory> get() { return new WeakHashMap<Configuration, SearchFactory>(2); } }; static { Version.touch(); contexts.set( new WeakHashMap<Configuration, SearchFactory>(2) ); } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
