[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2264) NPE when NamedQuery contains space before variable name

NPE when NamedQuery contains space before variable name ------------------------------------------------------- Key: HHH-2264 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2264 Project: Hibernate3 Type: Bug

Components: core Versions: 3.2.1 Environment: JDK 1.5.0_09-b03, JBoss 4.0.5 GA, MySQL 5.0.24a, mysql-connector-java-5.0.4 Reporter: Rüdiger Schulz Priority: Minor Fix For: 3.2.2

I just got a weird NullPointerException using Hibernate JPA. When creating my EntityManagerFactory, the usual logging started to appear and finished in stacktrace containing this: Exception in thread "main" java.lang.NullPointerException at org.hibernate.hql.ast.ParameterTranslationsImpl.getNamedParameterExpectedType(ParameterTranslationsImpl.java:63) at org.hibernate.engine.query.HQLQueryPlan.buildParameterMetadata(HQLQueryPlan.java:296) at org.hibernate.engine.query.HQLQueryPlan.(HQLQueryPlan.java:97) at org.hibernate.engine.query.HQLQueryPlan.(HQLQueryPlan.java:56) at org.hibernate.engine.query.QueryPlanCache.getHQLQueryPlan(QueryPlanCache.java:72) at org.hibernate.impl.SessionFactoryImpl.checkNamedQueries(SessionFactoryImpl.java:400) at org.hibernate.impl.SessionFactoryImpl.(SessionFactoryImpl.java:351) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1218) at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:691) I could root it down to a NamedQuery in one of my Entites; when commenting it out, the creation went through fine. The Query definition looked like this: @NamedQuery( name = "User.find", query = "SELECT user FROM User user WHERE user.id =: id" ) After some googling I found a solution on the Spring forum: it's the whitespace between the colon and the variable name. The error message should be more specific here, or better yet, the whitespace should not throw an error.
