>                 URL: https://issues.apache.org/jira/browse/GROOVY-11803
>             Project: Groovy
>          Issue Type: Bug
>            Reporter: Paul King
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 5.0.3

> The following script fails:
> {code:groovy}
> interface Foo {
>     default int barSize() { bar.size() }
>     String getBar()
> }
> class Baz implements Foo {
>     String getBar() { 'BAR' }
> }
> assert new Baz().barSize() == 3
> {code}
> With this error:
> {noformat}
> groovy.lang.MissingPropertyException: No such property: bar for class: Baz
> {noformat}
> Workaround 1: Use getter:
> {code:groovy}
> interface Foo {
>     default int barSize() { getBar().size() }
>     String getBar()
> }
> class Baz implements Foo {
>     String getBar() { 'BAR' }
> }
> assert new Baz().barSize() == 3
> {code}
> Workaround 2: use @CompileStatic:
> {code:groovy}
> @groovy.transform.CompileStatic
> interface Foo {
>     default int barSize() { bar.size() }
>     String getBar()
> }
> class Baz implements Foo {
>     String getBar() { 'BAR' }
> }
> assert new Baz().barSize() == 3
> {code}
> I think this is a bug but if we can't get this to work for dynamic Groovy, I think we need to improve the documentation.
