Re: [Springframework-developer] RE: About CGLIB2

[Rod J. <rod...@in...>]

I think upgrading before M4 is probably best too. So I will have to modif=
y
the AOP proxy...not that it's particularly hard.

Chris, I guess I'd better take another look at your examples of how we co=
uld
do away with CGLIB "optimization" in favour of CGLIB2 lazy interceptors o=
r
whatever they're called. Is there any documentation on the changes in CGL=
IB
and how to take best advantage of them, besides your excellent emails her=
e
:-)

Regards,
Rod

poses the question whether we should still release our 1.0 M4 with CGLIB1
support. Of course, our current codebase works nicely with Hibernate 2.1 =
as
long as you don't use CGLIB-based AOP proxies (i.e. proxy full target
objects instead of just interfaces), so we don't *have* to update
immediately.

Afterwards, it will be the other way round in terms of compatibility:
Hibernate 2.0 will still work with a current Spring release as long as yo=
u
don't use CGLIB-based AOP proxies. In any case, the most important rule i=
s
to just have the CGLIB version needed by your Hibernate version in the cl=
ass
path.

In the face of this situation, does everybody still prefer deferred CGLIB=
2
support at the time of our RC1? I vote for migrating already in M4, to al=
low
for CGLIB-based AOP proxies in combination with Hibernate 2.1 promptly.
After all, typical Spring users will choose to work with the most current
recommended Hibernate version.
