[ http://jira.jboss.com/jira/browse/JBAS-1579?page=comments#action_12316433 ] Clebert Suconic commented on JBAS-1579: ---------------------------------------
I thought the requirement for this would be to have serialUID defined in every single class. By using that method SerialUID will be calculated and I understood that we want to have them all defined. So...what's the requirement? - To have serialUID declared in every class? or - To have serialUID always compatible with previous versions? (in such a way that doesn't matter if it came defined or calculated) > Need to cleanup the serialVersionUIDs for Serializable/Externalizable classes > ----------------------------------------------------------------------------- > > Key: JBAS-1579 > URL: http://jira.jboss.com/jira/browse/JBAS-1579 > Project: JBoss Application Server > Type: Bug > Versions: JBossAS-4.0.2RC1, JBossAS-4.0.1 SP1 > Reporter: Scott M Stark > Assignee: Clebert Suconic > Priority: Blocker > Fix For: JBossAS-4.0.2 Final > Attachments: SerializableHasSerialVersionUIDField.zip, TestResultSample.zip, > compatibilityCheckProposedSourceCde.zip > > > I'm seeing incomptibilities between versions that are simply due to the fact > that Serializable/Externalizable classes are letting their serialVersionUIDs > float instead of explicitly defining them.
