----------------------------------

             Summary: Property shorthand not working for default methods in interfaces without @CompileStatic
                 Key: GROOVY-11803
                 URL: https://issues.apache.org/jira/browse/GROOVY-11803
             Project: Groovy
          Issue Type: Bug
            Reporter: Paul King


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.
