java - SerialVersionUID with "private static final long" still gets InvalidClassException -

-

i have compiled , jarred various projects in java application, generating serialversionuids automatically through eclipse classes derived serializable.

i read answers question, , verified serialversionuids private static final long.

nevertheless, error when try run:

java.io.invalidclassexception: com.acme.product.widget; local class incompatible: stream classdesc serialversionuid = 5226096973188250357, local class serialversionuid = -5432967318654384362

what missing?

you have classpath issue, program resolving older incompatible version of class has different value serialversionuid.

or serialized object being loaded, serialized oder version of class unavailable.
