you are using different class versions in your 2 java processes. Each seriazable class should have private static final long serialVersionUID = 9071843829692306762L; field declared.
LVL 12

The value does not matter. It should be different from one version to another version.

resolved when moving JAR to another platform, seems to be local configuration of tomcat/netbeans.
