Where are stored the generated Spring dynamic proxies?

Question

Can anyone please tell me where dynamic proxies (the bytecode) generated by the Spring framework are stored/held?

On the filesystem? In memory?

Answer 1

It is in memory - there is no bytecode enhancement of the class, but essentially a wrapper is created which intercepts all method calls to the wrapped class and delegates the calls to an InvocationHandler .
