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

             Summary: STC rejects program when passing method reference in 
parameterized function
                 Key: GROOVY-10975
                 URL: https://issues.apache.org/jira/browse/GROOVY-10975
             Project: Groovy
          Issue Type: Bug
          Components: Static Type Checker
            Reporter: Thodoris Sotiropoulos


Probably a regression because groovyc 4.0.10 compiles the program.

Program:

{code}
import java.util.*;

class Main {
  static final void test() {
    Collection<Integer> x = null;
    WeakHashMap<Integer, Integer> y = null;

    new Hashtable<java.lang.IllegalStateException, Boolean>(Collections.min(x, 
y::put));
  }
}
{code}

h3. Actual behavior

{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Main.groovy: 8: [Static type checking] - Cannot find matching constructor 
java.util.Hashtable(java.lang.Object)
 @ line 8, column 5.
       new Hashtable<java.lang.IllegalStateException, 
Boolean>(Collections.min(x, y::put));
       ^

1 error
{code}

h3. Expected behavior

Compile successfully

Tested against master (commit: d3c914693486bf137ec0992ef0dc28b79cba2fae)
