SPI package allowing Spring AOP framework to handle arbitrary advice types.
Users who want merely to use the Spring AOP framework, rather than extend
its capabilities, don't need to concern themselves with this package.
You may wish to use these adapters to wrap Spring-specific advices, such as MethodBeforeAdvice,
in MethodInterceptor, to allow their use in another AOP framework supporting the AOP Alliance interfaces.
These adapters do not depend on any other Spring framework classes to allow such usage.
