Description

Hi all,
I'm extending class ODataJPAQueryExtensionEntityListener in order to modify the sql query to our needs in getQuery methods. In some cases I like to return no entry / query (e.g. the user has not the sufficient role) which is not possible currently as the default query will be build in case one returns null see

https://github.com/apache/olingo-odata2/blob/master/odata2-jpa-processor/jpa-core/src/main/java/org/apache/olingo/odata2/jpa/processor/core/access/data/JPAQueryBuilder.java#L74

on the other hand there are cases in which I like to throw and error message of type ODataException in method getQuery to propagate this information to the consumer instead of returning an empty list.

Best
Alex
