[jira] [Created] (GROOVY-11853) breaking changes for inner class methodMissing and propertyMissing protocol

Eric Milles created GROOVY-11853:
------------------------------------

             Summary: breaking changes for inner class methodMissing and propertyMissing protocol
                 Key: GROOVY-11853
                 URL: https://issues.apache.org/jira/browse/GROOVY-11853
             Project: Groovy
          Issue Type: Bug
          Components: groovy-runtime
    Affects Versions: 6.0.0-alpha-1
            Reporter: Eric Milles
            Assignee: Eric Milles


There were some scenarios that allowed access to an object's outer class members that no longer work under the GROOVY-11823 redesign.

1) access to outer class field through object expression:
{code:groovy}
class Outer {
  class Inner {
  }
  def p = "p"
}
def o = new Outer()
def i = new Outer.Inner(o)
println i.p
{code}

2) outer class invokeMethod or other such MOP overloads:
{code:groovy}
String string = new Object() {
  @Override String toString() {
    // outer class is a Script and overrides getProperty, setProperty and invokeMethod
    dynamicVariable = "foo"
  }
}
println dynamicVariable
{code}
