I have a web app that is using Airavata API to access Provenance information. I'm getting
following exception when retrieving information from the backend.

This means that your application will be less efficient and will consume more memory than
it would if you ran the OpenJPA enhancer. Additionally, lazy loading will not be available
for one-to-one and many-to-one persistent attributes in types using field access; they will
be loaded eagerly instead.
