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
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.
