/**
* FactoryBean that exposes a TimerTask object that delegates
* job execution to a specified (static or non-static) method.
* Avoids the need to implement a one-line TimerTask that just
* invokes an existing business method.
*
* Derives from MethodInvokingRunnable to share common properties
* and behavior, effectively providing a TimerTask adapter for it.
*
*
Often used to populate a ScheduledTimerTask object with a specific
* reflective method invocation. Note that you can alternatively populate
* a ScheduledTimerTask object with a plain MethodInvokingRunnable instance
* as well (as of Spring 1.2.4), without the need for this special FactoryBean.
