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 Assignee: Emmanuel Bernard Fix For: FIRST

Original Estimate: 3 minutes Remaining: 3 minutes 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) ); }
