NullPointerException in org.hibernate.util.ComparableComparator --------------------------------------------------------------- Key: HHH-1866 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1866 Project: Hibernate3 Type: Bug

Versions: 3.2.0.cr2 Environment: - Hibernate 3.2.0 CR2 - Spring 1.2.5 - JBoss Cache 1.4 - Oracle 9i - Windows and Linux Reporter: Eduard Hildebrandt Attachments: OptimisticTreeCache.patch I think that org.hibernate.util.ComparableComparator or OptimisticTreeCache.DataVersionAdapter has a bug. "return ((Comparable) x).compareTo(y);" throws a NullPointerException if x is a null pointer. org.hibernate.util.ComparableComparator. compare(..) is called from OptimisticTreeCache.DataVersionAdapter in line "return versionComparator.compare( previousVersion, other ) > 1;". We get this NullPointerExption if we use Hibernate with org.hibernate.cache.OptimisticTreeCacheProvider which causes an org.springframework.transaction.UnexpectedRollbackException.
