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

             Summary: Unexpected type mismatch when having overloaded methods 
with variable arguments
                 Key: GROOVY-11002
                 URL: https://issues.apache.org/jira/browse/GROOVY-11002
             Project: Groovy
          Issue Type: Bug
          Components: Static Type Checker
            Reporter: Thodoris Sotiropoulos


I have the following program

{code}
import java.util.function.Supplier;

class Main {
  static final void test() {
    Main.<String>m(() -> "df", "fdaf");
  }

  static <T> void m(Supplier<T> x, T... y) {}
  static <T extends Comparable<? extends T>> void m(T...y) {}
}
{code}

h3. Actual behavior

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 5: [Static type checking] - Cannot return value of type 
java.lang.String for lambda expecting int
 @ line 5, column 26.
       Main.<String>m(() -> "df", "fdaf");
                            ^

1 error
{code}

h3. Expected behavior

Compile successfully

h3. Notes

Tested against master (commit: a4e0d6de9cc2d8ecb48b48df501e63ec1735d837)

Test case adapted from:

{code}
class Main {
  static final void test() {
    org.apache.commons.lang3.ObjectUtils.<String>median((stills, impeaches) ->  
 86 , "fdaf");
  }
}
{code}
