Construct a new JdkDynamicAopProxy for the given AOP configuration.

Parameters:

config - the AOP configuration as AdvisedSupport object

Throws:

AopConfigException - if the config is invalid. We try to throw an informative exception in this case, rather than let a mysterious failure happen later.

Equality means interfaces, advisors and TargetSource are equal.

The compared object may be a JdkDynamicAopProxy instance itself or a dynamic proxy wrapping a JdkDynamicAopProxy instance.

Implementation of InvocationHandler.invoke.

Callers will see exactly the exception thrown by the target, unless a hook method throws an exception.
