> Attached is a patch and test case for an issue in the bean binding code which prevents
binding to an overloaded method with a covariant return type from the base class. 
> The fix is to check for method covariance at the last moment before throwing AmbiguousMethodCallException.
If all methods remaining are covariant, any one of them can be called. Unfortunately this
happens in 3 places in the code- if we pre-filtered the list of methods then we could lose
annotations on either of the method signature which could be problematic depending on the
resolution type.
