Key: JBAS-4295

Project: JBoss Application Server
Issue Type: Task
Security Level: Public(Everyone can see)
Components: CMP service
Affects Versions: JBossAS-5.0.0.Beta1, JBossAS-4.0.5.GA, JBossAS-4.2.0.CR1
Reporter: Alexey Loubyansky
Assigned To: Alexey Loubyansky
Fix For: JBossAS-4.2.0.GA, JBossAS-5.0.0.Beta2, JBossAS-5.0.0.Beta3
java.lang.NullPointerException
at
org.jboss.ejb.plugins.cmp.jdbc2.bridge.JDBCCMRFieldBridge2$CollectionValuedFieldState.loadOnlyFromCache(JDBCCMRFieldBridge2.java:1085)
was caused by calling size() on a CMR collection w/o a transaction. It would be better to
throw an exception with a message explaining the problem.
