> Project: Groovy
> Issue Type: Bug

> The following code can not run when STC is enabled:

> import java.util.stream.Collectors;
> @groovy.transform.CompileStatic
> def m() {
> Map<String, Integer> map = new HashMap<>();
> map.put("a", 1);
> map.put("b", 2);
> final Map<String, Integer> result =
> map.entrySet().stream().collect(Collectors.toMap(e -> e.getKey(),
> e -> e.getValue(), (v1, v2) -> v1));
> return result;
> }
> assert [a:1, b:2] == m();
> {code}
> Here are the error messages:
> {code:java}
> 3 compilation errors:

> java.lang.Object#getKey(). Please check if the declared type is correct and
> if the method exists.
