Hello,
We move from Kodo to Hibernate and because proxies did not meet the requirements of our business layer (narrowing proxy and casting problems), we decided to use bytecode enhancement in order to avoid lots of changes in our business layer.
However, lazy loading interception does not work for us.
What I did is I put annotation on every entity class and annotation on every field that that is or association, so it looks in most cases like:

(We had to put that cascade because Kodo used defferred constraints mechanism which is unavailable in Hibernate afaik)
Bytecode Instrumentation task worked and modified compiled classes what can be seen after decompiling.
However if I run a JPQL query like select queries for every @ManyToOne association are issued as well.
Are we missing something important?
We use Hibernate 4.2.18

Hibernate 4.2 is too old and many things have changed ever since.

Try with 5.2 or 5.1 and see how it works.

But then, related to this statement:



Maybe you should investigate why the default Proxy mechanism is not working for you. Relying on BE for lazy loading is only needed for lazy @Basic properties or the parent-side @OneToOne.

However, if that's not the case, then you are over-complicated things and gain too little in return.
