Whenever I click on logout link from Liferay,It shows below Exception in the console however i am able to logout sucessfully.

Could not deserialize session data.java.io.InvalidClassException: org.hibernate.proxy.pojo.javassist.SerializableProxy; local class incompatible: stream classdesc serialVersionUID = 1180036893511205383, local class serialVersionUID = -2265249369383210104
at java.io.ObjectStreamClass.initNonProxy(ObjectStreamClass.java:560)

It seems to be Classpath polluted with different hibernate jars.But still not able to figure it out.Below is the jar files which i have in classpath.

hibernate-annotations.jar
hibernate-commons-annotations.jar
hibernate-core.jar
hibernate3.jar

Environment: Liferay 6.0
Application Server: Weblogic 10.3
Any Help would be much appreciated.


Thanks
