Description

Just encountered the following issue :

2011-03-04 15:18:19,916 ERROR c.a.t.t.w.s.i.ExceptionLogger : java.io.InvalidClassException: com.accor.tars.tools.api.enterprise.chain.Chain; local class incompatible: stream classdesc serialVersionUID = 9011182591418795268, local class serialVersionUID = -7286565524645379272 from ActionInvocation class com.opensymphony.xwork2.DefaultActionInvocation

It could be nice if this could be quietly (only a warn ?) ignored (at least with a new configuration parameter) and the element remove from the disk.

Greg what do you think about this?

Seems of questionable value to do internally in the cache, seems more like a app level decision

If we were to do it though I’m not sure I’d limit the behavior to the disk store – seems like any deserialization error on read should cause this auto-remove.
