Java 8 generic function should be ambiguous, but failing in runtime

Question

I\'m trying to migrate Java 7 code to Java 8, so I\'ve code similar to:

package tests;

import java.util.Arrays;
import java.util.Map;

public class Tests {
             


        

Answer 1

Yeah, I have no idea why Java 8 is choosing the overload that takes a map over the one that takes the Comparable vararg. I'm going to guess that good old type erasure is at play here.

That said, I would just make getString() return a Comparable rather than a T.
