>                 URL: https://issues.apache.org/jira/browse/GROOVY-7859
>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>    Affects Versions: 2.4.7
>            Reporter: Shil Sinha
>
> The following currently passes static type checking:
> {code}
> @groovy.transform.CompileStatic
> void test() {
>   def x = String.&length
>   x()
> }
> test()
> {code}
> At runtime, it fails with:
> {quote}
> java.lang.IllegalArgumentException: object is not an instance of declaring class
> {quote}
> If {{String.&length}} is replaced with {{String.&size}}, or a pointer to any extension method, it still passes STC, but fails with a ClassCastException instead.
