I've committed this change (ability to specify arbitrary init method without depending on a Spring interface). See initializers.xml in the XML bean factory test suite for an example of using the new "init-method" attribute. Custom initializers can throw any exception; the only restriction is that they may have no arguments.

I think we must keep InitializingBean however. Many framework classes depend on it and we should not force users to know the relevant init method that they may not care about, and we must not force users to remember to set the magic initialization attribute to get the AOP framework etc to work. So I propose: - Keep InitializingBean - Add a new "init-method" attribute for arbitrary methods. If a class implements both IB and has an initializer, the IB method will be called first. If the user specifies an init-method att and there's no such method that's treated as a fatal exception.

No Spring specific Exception has to be waited for. The called method can have or not a throws statement and it can always throw a RuntimeException. The factory will have to catch any Exception and throwing itself a ServletException? If an initialization method throws any kind of Exception, it's allways fatal. So we can gain a new design step.

What you think about this? +1 I see no disadvantages, and it would be nice to not having to depend on any Spring interfaces at all.
