Description

Consider the following:

import java.util.function.Supplier

@groovy.transform.CompileStatic
class C {
  private String getX() { 'x' }
  void test() {
    Supplier<String> s = () -> x // GroovyCastException: Cannot cast object 'class C' with class 'java.lang.Class' to class 'C'
    print s.get()
  }
}

new C().test()

If variable expression "x" is replaced by "getX()" this runs successfully. Also works if lambda is replaced by closure. And not compile static works too.
