As a general rule we only guarantee JCR and jackrabbit-api compatibility 
across major and minor releases.

We try to keep also internal jackrabbit-core interfaces like 
PersistenceManager and AccessManager fairly stable, but every now and 
then we need to change those to achieve various benefits. It's expected 
that people who customize such internal components keep track of the 
developments within jackrabbit-core and are ready to adapt their code as 
needed or to suggest (and implement) alternatives that don't require 
changing the interfaces.
