>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>    Affects Versions: 4.0.24
>            Reporter: Saravanan
>            Priority: Minor
>
> {code:java}
> public class Interfaces {
>     public String myThing() {
>         var myArray = Arrays.asList("123", "1354");
>         var mySet = myArray.stream().collect(Collectors.toSet());
>         
>         // This call will fail
>         //      Failed to find class method 'getBytes(java.lang.Object)' or
>         //      instance method 'getBytes()' for the type: java.lang.String
>         // To make it work change the previous line to
>         //      var mySet = myArray.stream().collect(Collectors.<String>toSet());
>         mySet.forEach(String::getBytes);
>     }
> }{code}
> Most Collectors.<methods> need a fully qualified type for the generic parameter, without which the compile will fail (sometimes detect an Object type instead of the right one)
