Re: [jboss-dev] JBoss-5.0 GA and JBoss-5.0.1 GA incompatible?

Well Jaikiran really means that changing the serialVersionUID for SimplePrincipal breaks serialization compatibility with AS 5.0.1.GA https://jira.jboss.org/jira/browse/SECURITY-341 But I understand what is fixed here is having serialVersionUID compatibility with older 4.2.x releases. The only way to have both is using special flags to switch IDs at load time, there is no other way. Obviously the mistake was that serialVersionUID for SimplePrincipal changed in AS 5.0 but I'm curious how we didn't catch this in the SerialVersionUIDUnitTestCase. It turns out we didn't check for libs in JBOSS_HOME/lib and JBOSS_HOME/server/all, so when JBOSS_HOME/common/lib was added we've missed the libs in there. Also, shouldn't errors of this type show in some of the compatibility matrix tests?
