InvalidClassException: com.sun.rowset.providers. RIOptimisticProvider; local class incompatible: stream classdesc serialVersionUID

i ran into this weird exception when im trying to connecting a Swing Application + Crystal Report to a database via EJB. I dont know why, but this error always happen only at reporting module. And what makes it weird that this exception only happen at several terminals only.

java.rmi.RemoteException: null; nested exception is: 
	java.io.InvalidClassException: com.sun.rowset.providers.RIOptimisticProvider; local class incompatible: stream classdesc serialVersionUID = -3143367176751761936, local class serialVersionUID = -8429279896237029122

after some research i found out that this exception happen only to terminals using JRE 1.60 update 7 or less.

C:\Users\edw>java -version
java version "1.6.0_07"
Java(TM) SE Runtime Environment (build 1.6.0_07-b06)
Java HotSpot(TM) Client VM (build 10.0-b23, mixed mode, sharing)

this exception gone after i updated every terminal’s JRE into JRE 1.60 update 19

C:\Users\edw>java -version
java version "1.6.0_19"
Java(TM) SE Runtime Environment (build 1.6.0_19-b04)
Java HotSpot(TM) Client VM (build 16.2-b04, mixed mode, sharing)

And now i have to update every terminals that are still using JRE 1.6.0_07. Weird eh, hahahaa…..
