Description
Several real world packages use factories (see GoF pattern) to create new instances of a type. These are hard to integrate into Pico, since there is neither a ctor nor a setter interface for initialization. Leo Simons proposed a nice light weight wrapper on the list as a common solution to this problem:

Next use case:
MBeanServer server = MBeanServerFactory.createMBeanServer();
Aslak / Paul,
can I add this adapter to Pico?
Assign me this issue ...

Jörg This looks OK to me. It qualifies for PicoContainer (no external package deps, no reflection, no meta-data).
Should it go in a package other than default ?
Aslak ?

Aslak ? I think subclassing ComponentAdapter would be more flexible solution.
I'm playing with hibernate component adapters right now, and
( for example ) SessionFactoryComponentAdapter provides hibernate session factory, and has dependency to hibernate configuration.
( which is easily subclassed to be constructable )
And this component adapter can be wrapped by caching one.
The same is for hibernate session - dependency on SessionFactory.class
( which is provided by adapter ) and wrapping by caching / thread local adapter ( for example )

I think this could be useful for a lot of real world situations. This is a clean and lightweight solution.
