Description

class Root {
  Parent parent = new Parent()

  def parent(@DelegatesTo(Parent) Closure cl) {
    cl.delegate = parent
    cl()
  }
}

class Parent {
  Child child = new Child()

  def child(@DelegatesTo(Child) Closure cl) {
    cl.delegate = child
    cl()
  }

  def foo() { "parent" }
}

class Child {
  def foo() { "child" }
}

@groovy.transform.CompileStatic
def usage() {
  new Root().parent {
    child {
      foo()
    }
  }
}

println usage()

Expected result: parent
Actual result: child

Closure inside child {} call has default resolve strategy, i.e. owner first. Its owner is a closure passed to parent {}, which is delegated to Parent, which in turn has the method foo.

Works properly without @CompileStatic.
