Error while serializing concept www.tibco.com/be/ontology/Concepts/Preferences
        at com.tibco.be.functions.object.ObjectHelper.serializeUsingDefaults(ObjectHelper.java:495)



Cause:

=====

Usually this error is thrown when you are using an Enterprise Archive File (EAR) file built on the latest BE version and running this on a BE installation with older libraries. For example, if the ear file is compiled with BE 3.0.0 + HF1 libraries and is running on a BE 3.0.0 environment.


Resolution:

=========

Enable debug logs if possible and check the log information during the engine startup. If you see a version mismatch (between compiled and runtime versions), then apply the latest build to your running environment, rebuild the ear with the latest BE install and start the engines.
