@PublicApi can expect
that programs compiled against a given version will remain binary compatible with later versions of the
@PublicApi as per each product's API policy as long as the client does not implement/extend
@PublicApi interfaces or classes (refer to each product's API policy for the exact
guarantee---usually binary compatibility is guaranteed at least across minor versions).
@PublicApiinterfaces and classes are not designed to be implemented or extended by clients, we may perform certain types of binary-incompatible changes to these classes and interfaces, but these will not affect well-behaved clients that do not extend/implement these types (in general, only classes and interfaces annotated with
@PublicSpiare safe to extend/implement).
This exception is thrown when the data store exception is caught by the persistence code. As there is very little that can be done about persistence exception on the "business logic" layer of the application this is a Runtime exception.
