[jira] [Commented] (GROOVY-9779) Inconsistency with callable properties in static context

Eric Milles (Jira)

    [ https://issues.apache.org/jira/browse/GROOVY-9779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17212406#comment-17212406 ]

Eric Milles commented on GROOVY-9779:
-------------------------------------

{{MetaClassImpl#invokeStaticMethod}} does this at the end:
{code:java}
        if (prop != null) {
            MetaClass propMC = registry.getMetaClass(prop.getClass());
            return propMC.invokeMethod(prop, CLOSURE_CALL_METHOD, arguments);
        }

        return invokeStaticMissingMethod(sender, methodName, arguments);
    }
{code}

This is where a non-closure property is tried as a callable.  {{invokeMethod}} ends with [{{invokePropertyOrMissing}}|https://github.com/apache/groovy/blob/master/src/main/java/groovy/lang/MetaClassImpl.java#L1315] which does not try the property as callable unless it is a closure or a script binding variable.

> def container = new Container()
> assert container.staticC() == 42 // MissingMethodException

> I'd expect the invocations to fail or to work in both static and instance contexts.
