ReflectionLifecycleStrategy should support "null" methods
---------------------------------------------------------

                 Key: PICO-379
                 URL: http://jira.codehaus.org/browse/PICO-379
             Project: PicoContainer
          Issue Type: Improvement
          Components: PicoContainer (Java)
         Environment: Affects 2.12, which is not available here.
            Reporter: Grégory Joseph
         Attachments: ReflectionLifecycleStrategy-support-null.patch

I want to support a legacy lifecycle pattern in our code where we only have one {{init()}} method, no stop/dispose methods. Ideally I guess I should be able to use this lifecycle strategy:
{{                new ReflectionLifecycleStrategy(componentMonitor, "init", null, null)}}
but this fails miserably with NPEs in java.lang.Class.

The attached patch allows this, thus keeping me from having to do
{{                new ReflectionLifecycleStrategy(componentMonitor, "init", "some-really-stupid-method-name-that-won't-exist", "some-really-stupid-method-name-that-won't-exist-either")}}
