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.

Hmm, maybe this was once the case, but I am not sure it is so easy any 
longer. I tried dropping in Hibernate 2.1 final (with cglib2). However, 
when using TransactionProxyFactoryBean, which no longer has the old 
ProxyInterfacesOnly boolean option (which used to default to true, and 
used a JDK proxy in the true case instead of cglib proxy), I now get an 
exception

java.lang.NoClassDefFoundError:

The offending line is:

  ProxyFactory proxyFactory = new ProxyFactory();

Of course, ProxyFactory extends AdvisedSupport, which directly 
references OptimizedCglib1AopProxy.
