--------------------------------------

             Summary: Can't use parameter type to select among overloaded methods
                 Key: CAMEL-10396
                 URL: https://issues.apache.org/jira/browse/CAMEL-10396
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 2.18.0
         Environment: Ubuntu 14.04
            Reporter: Alex Dettinger
            Priority: Minor


I've noticed that the overload selection mechanism based on parameter types is not working
when some parameters are assignable, in the sense of Class.isAssignableFrom(...).

Given those methods:
String toString(String input)
String toString(int input)
We can select both methods via bean:toString(String) or bean:toString(int)

But given those methods:
String toString(String input)
String toString(Object input)
bean:toString(String) end in selecting toString(Object).

Ideally, I would expect it to select toString(String). Otherwise, unwinding an AmbiguousCallException
may perhaps apply.

Thoughts:
I'm wondering whether ObjectHelper.isOverridingMethod(...) would be mixing overload vs override.

Will attach a test case.
