I'm using 4.3.4.Final and I have the same problem, the association ManyToOne does not initialize until that associated entity is accessed, probably the bigger issue comes with the extra query that causes a database access and LazyInitializationException if the object becames detached even though all associations were preloaded with a JOIN FETCH.
I can't use proxy and i think this bug makes completely unuseful lazy no-proxy and fetch strategy with instrumentation.
