NPE in org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.getStatus ------------------------------------------------------------------------------ Key: HHH-7109 URL: https://hibernate.onjira.com/browse/HHH-7109 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.1.0 Environment: hibernate-jpa-2.0-api:1.0.1-Final; hibernate-core:4.1.0.Final; hibernate-entitymanager:4.1.0.Final Reporter: Michael Nascimento Santos Priority: Minor When using JPA with Hibernate as the persistence provider and a vanilla persistence.xml, the following exception is produced: java.lang.NullPointerException at org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.getStatus(JtaStatusHelper.java:73) at org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.isActive(JtaStatusHelper.java:115) at org.hibernate.engine.transaction.internal.jta.CMTTransaction.join(CMTTransaction.java:149) at org.hibernate.ejb.AbstractEntityManagerImpl.joinTransaction(AbstractEntityManagerImpl.java:1208) at org.hibernate.ejb.AbstractEntityManagerImpl.postInit(AbstractEntityManagerImpl.java:177) at org.hibernate.ejb.EntityManagerImpl.<init>(EntityManagerImpl.java:89) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:132) at org.hibernate.ejb.EntityManagerFactoryImpl.createEntityManager(EntityManagerFactoryImpl.java:127) This is due to the fact the new, undocumented property, hibernate.transaction.jta.platform hasn't been set. However, since a NPE is thrown, the user has no way of figuring out what needs to be done to solve this. -- This message is automatically generated by JIRA.
