Javers throws exception when property is null

I have this issue where, if a property of a composite is null (note it's not the ID), Javers throws an exception:

JaversException PROPERTY_ACCESS_ERROR: error getting value from property 'Method User getPersonEntity; //declared in: HibernateProxy_$$_javassist_356' on target object of type 'HibernateProxy_$$_javassist_356', cause: java.lang.reflect.InvocationTargetException: null

or 

JaversException PROPERTY_ACCESS_ERROR: error getting value from property 'Method List getAddress; //declared in: ... **Object property of the audited object**, cause: java.lang.reflect.InvocationTargetException: null

So, imagine the following structure:

User contains Person, which contains Address - all objects with their own properties.

If I commit a User object, if either Person or Address has a null property, Javers fails with the above error.

How does Javers handle null properties? Can it be configured to just not log a null property or to log it as null? I can't see a reason why it should throw an exception when a property is null?! There doesn't seem to be any documentation about how null properties are handled.

JaVers deals with nulls without any problems, but your getter didn't return null but thrown exception. Seems your object is a Hibernate dynamic proxy and cant'b be initialized.
