* *I want to draw your attention to some notable changes in previous

o *Build 14* - Classes are now loaded and linked by
Class.forName() (JDK-8212117
<https://bugs.openjdk.java.net/browse/JDK-8212117>)
+ we need help testing changes to 3-arg Class.forName method.
The method has always been specified to link the class but
the implementation has historically not done this when
invoked with the "initialize" parameter set to false. The
bug has been fixed in JDK 14 but it has the potential to
change the behavior of code that uses Class.forName to load
classes that cannot be linked.

Narrowed HibernateProxy and Uninitialized bytecode-enhanced entities do not get detached
by Gail Badner
Hi,
I seem to remember this topic came when we were working on the
enhancement-as-proxy feature.
Basically, EnhancementAsProxyLazinessInterceptor#session does not get
nullified when the PersistenceContext gets cleared.
As a result, such an entity can still get initialized if
the SharedSessionContractImplementor is still open.
I also noticed that narrowed proxies are never added to the
PersistenceContext, but they still have a reference to
the SharedSessionContractImplementor from which the narrowed proxy
originated. These references never get nullified either.
I believe these are both bugs, and I would like to address them.
Please let me know if I'm missing something here.
Thanks,
Gail

HHH-13604 Define some Byteman rules to check what APIs are used at runtime: next steps?
by Fabio Massimo Ercoli
Hi guys,
the activity was very interesting, so I would like to thank Sanne who had
the idea and led the scope of the activity and thanks to Andrea who gave me
some nice ideas to improve the work.
With [this pull request](
https://github.com/hibernate/hibernate-orm/pull/3040) we have now rules to
check:
Read annotations
Class.forName
Other Java reflection APIs
Create proxy
Patter#compile
As a follow up (and probably it won’t be the only one) I created the issue:
https://hibernate.atlassian.net/browse/HHH-13669.
So far I’ve been involved in Hibernate OGM and Hibernate Search, so I don't
have a very deep knowledge of Hibernate ORM. So I would like to ask you:
what are the next steps?
And… is there something I can do to help?
Meanwhile I’ll be back to work on Hibernate Search. The integration with
Infinispan is still waiting…
Have a great weekend
Fabio
