-/**
- * An implementation provider for sample CRUD implementations.
- *
- * The implementation provider is responsible for handling the lifecycle of a component
- * implementation and creating operation invokers for the service operations provided
- * by the implementation.
- *
- * The start() and stop() methods are called when a component is started
- * and stopped. In this example we are using that opportunity to call init and destroy methods
- * on the POJO instance if these methods exist.
- *
- * The createInvoker method is called for each operation provided by the component
- * implementation. The implementation provider can create an invoker and initialize it
- * at that time to minimize the amount of work to be performed on each invocation.
- *
- * For example here we are looking up the Java method corresponding to the service operation
- * at passing it to the invoker constructor. This way the invoker won't have to lookup the Java
- * method on each invocation.
