Description
I need a lazy lifecycle strategy within Pico, as in one that will start a component only once it is required. Currently container.start() will eagerly instantiate lifecycled components before they are actually needed. I'd like to intercept when components are instantiated and start them before they are used.
Activity
Reopening since the fix doesn't fulfil the original requirements.

You'll have to extend DefaultPicoContainer to make it work, but it should be what you want.

added a comment - Attaching PICO-355 -test3.patch to improve test by not attempting to restart a started component. Found a problem with the current solution: an ISE is thrown when the container is disposed if the component hasn't been instantiated. PICO-355-test4.patch demonstrates the problem.
