getDefaultAccessType

public org.hibernate.cache.access.AccessType getDefaultAccessType()

Default access-type used when the configured using JPA 2.0 config. JPA 2.0 allows @Cacheable(true) to be attached to an entity without any access type or usage qualification.

We are conservative here in specifying AccessType.READ_WRITE so as to follow the mantra of "do no harm".

This is a Hibernate 3.5 method.
