> A promoted trait static that calls a @Virtual static fails with 
> MissingMethodException when called through the trait

>                 Key: GROOVY-12604
>                 URL: https://issues.apache.org/jira/browse/GROOVY-12604
>             Project: Groovy
>          Issue Type: Bug
>    Affects Versions: 6.0.0
>            Reporter: Scott Murphy Heiberg
>            Priority: Major
>
> {code:groovy}
> import groovy.transform.Virtual
> trait T {
>     @Virtual static String setting() { 'default' }
>     static String describe() { 'setting=' + setting() }
> }
> class C implements T {}
> assert C.describe() == 'setting=default'
> assert T.describe() == 'setting=default'
> {code}
> Actual: {{T.describe()}} throws {{MissingMethodException: No signature of 
> static method: setting for class: T is applicable for argument types: () 
> values: []}}. This happens in dynamic Groovy, with @TypeChecked and with 
> @CompileStatic. The trait documentation's own @Virtual example fails the same 
> way when called as {{Configurable.describe()}}.
> Expected: called through the trait itself there is no implementing class, so 
> the trait's own (default) implementation of the @Virtual static is used, and 
> the call returns {{setting=default}}.
> Public trait statics are promoted to the trait interface, and the forwarder 
> passes the trait interface as the static self. The @Virtual call site 
> dispatches dynamically on that self, but @Virtual statics are deliberately 
> not promoted to the interface, so the call finds nothing.
> Seen in 6.0.0 (the first version with @Virtual).
