CAMEL-11235: Proposal to fix an issue where a method inherited from a superclass overrides a superinterface method
This PR proposes a fix for [CAMEL-11235](https://issues.apache.org/jira/browse/CAMEL-11235).
Basically, the `BeanInfo` introspection mechanism traverses the single rooted class hierarchy collecting overrides first, and then proceed with interfaces.
I've also created a new overload of `ObjectHelper.isOverridingMethod(...)` to deal with the case where a method inherited from a class [overrides a superinterface method](https://docs.oracle.com/javase/specs/jls/se8/html/jls-8.html#jls-8.4.8.1).
