Hibernate envers: merge & saveOrUpdate

Question

I am working on a spring-hibernate-envers application. After many search jobs finally work for me, but I still have a couple of questions.

I used saveOrUpdateto save or update objects. But when dealing with throwing a nonUniqueObject exception. So I used mergeinstead and it worked. Is it right to use merge for this? Does mergeinserts insert new objects for db?
I tried the following code:

entity=merge(entity);  
saveOrUpdate(entity);

That also worked. Is it correct? And also I am curious why saveOrUpdatenot throwing any errors now.
