InvalidClassException: org.jnp.interfaces.MarshalledValuePair
-------------------------------------------------------------
Key: JBAS-67
URL: http://jira.jboss.com/jira/browse/JBAS-67
Project: JBoss Application Server
Type: Bug
Components: Naming
Versions: JBossAS-4.0.0 Final
Reporter: Scott M Stark
Assigned to: Scott M Stark
Fix For: JBossAS-4.0.1 Final
The following exception is seen when a 4.0.1RC1 client talks to the 4.0.0
naming service:
java.io.InvalidClassException: org.jnp.interfaces.MarshalledValuePair; local
class incompatible: stream classdesc serialVersionUID = -6485622724173581497,
local class serialVersionUID = -3403843515711139134
The problem is due to the introduction of a serialVersionUID that is compatible
with the 3.2.x version. Even though there has been no actual serializable
incompatible changes, because the serialVersionUID has not been assigned any
change in the class resulted in the implicit serialVersionUID changing. So even
though the MarshalledValuePair is compatible with 4.0.1RC1 and 3.2.6, the lack
of an explicit serialVersionUID to this effect has resulted in an
incompatibility. At this point I don't think there is anyting that can be done
about the 4.0.0 incompatiblity unless 3.2.x incompatibility is introduced.
