Summary: Fail to find method reference in case of chain of

Project: Groovy
Issue Type: Bug
Components: Static Type Checker
Reporter: Thodoris Sotiropoulos
This is probably a regresssion.
I have the following program
{code}
import java.util.*;
import java.util.concurrent.*;
class Foo<K, V> {
V apply(K p) { return null; }
}
class Main {
static final void test(Foo<Map.Entry<Number, Boolean>, String> p) {
ConcurrentHashMap.KeySetView<Number, Boolean> x = null;
ConcurrentHashMap<Number, Boolean> y = x.getMap();
y.<String>reduceEntries(19, p::apply, null); // works
x.getMap().<String>reduceEntries(19, p::apply, null); // fails
}
}
{code}
h3. Actual behavior
{code}
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
