Change semantics of add() and or() methods in Criteria

In my opinion, the Criteria.add() and Criteria.or() method behave counter-intuitively. My opinion of an intuitive behaviour would be:

• Criteria.or(someCondition) should result in a where clause which contains ((whatever was in the where condition before) OR someCondition)
• Criteria.add(someCondition) should result in a where clause which contains ((whatever was in the where condition before) AND someCondition), i.e. the same as Criteria.and(someCondition)

Instead, the behaviour is now

• Criteria.or(someCondition) only or's the new condition with any existing condition(s) that affects the same column.
• Criteria.add(someCondition) replaces any existing condition(s) that affects the same column with the new condition.
