/**
 * {@link FactoryBean} that exposes a {@link TimerTask} object which
 * 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.
 *
 * <p>Derives from {@link MethodInvokingRunnable} to share common properties
 * and behavior, effectively providing a TimerTask adapter for it.
