RemoteAccessException does not have the serialVersionUID defined [SPR-4826]

[spring-projects-issues]

Gabriel Rosu opened SPR-4826 and commented

Having two tiers of the application on two physical boxes running SunOS 5.10 and sun's JDK 1.4.2_13 we're running into a deserializing problem when one of them throws an exception against the other. Here's the stacktrace:

2008-05-01 00:05:06,158 ERROR [ExecuteThread: '87' for queue: 'weblogic.kernel.Default'] svc.impl.InventorySvcImpl - java.rmi.UnmarshalException: Problem deserializing error response; nested exception is:
java.io.InvalidClassException: org.springframework.remoting.RemoteAccessException; local class incompatible: stream classdesc serialVersionUID = 3787812861223238444, local class serialVersionUID = -4906825139312227864

Note that our embedded exception has the serializeVersionUID set and we have the same version of it on both tiers; also have the same spring 2.0.8 version on both tiers.
We did notice that the RemoteAccessException does not have the serialVersionUID defined and we looked to see if version 2.5 would have that but it's still missing so upgrading spring would not help.

Affects: 2.0.6, 2.0.8

Backported to: 2.0.9

This is surprising since if there's the very same version of the Spring RemoteAccessException class on both sides, then the default serialVersionUID calculated by the JDK should be the same - and hence be considered compatible.

In any case, I've declared -4906825139312227864L as explicit UID now, which should be backwards compatible with both Spring 1.2 and 2.0. This will be available as of Spring 2.5.5 and 2.0.9.
