> Key: GROOVY-10975
> URL: https://issues.apache.org/jira/browse/GROOVY-10975
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Reporter: Thodoris Sotiropoulos
> Assignee: Eric Milles
> Priority: Minor
> Fix For: 5.0.0-alpha-2, 4.0.15, 3.0.20

> 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)
