Finds an accessible method that matches the given name and has compatible parameters.
Compatible parameters mean that every method parameter is assignable from the given parameters.
In other words, it finds a method with the given name that will take the parameters given.

<p>This method can match primitive parameter by passing in wrapper classes. For example, a
{@code Boolean} will match a primitive {@code boolean} parameter.

@param cls find method in this class
@param methodName find method with this name
@param parameterTypes find method with most compatible parameters
@return The accessible method
Finds an accessible method that matches the given name and has compatible parameters . Compatible parameters mean that every method parameter is assignable from the given parameters . In other words it finds a method with the given name that will take the parameters given .
