Paul King commented on GROOVY-11899:
------------------------------------
Claude's analysis:
{quote}The Fix (in Groovy compiler)
The stub generator (in the Groovy compiler source, likely in
JavaStubGenerator or similar) needs to either:
1. Add a dummy body to static methods in trait stubs, e.g.:
static java.lang.String getMessage() \{ return null; }
2. Omit static methods from trait stubs entirely, since they live on the
trait's helper class (TraitWithStaticMethods$Trait$Helper) at runtime, not on
the
interface itself.
Option 2 is arguably more correct — Groovy trait static methods aren't really
Java interface static methods; they're implemented on a companion helper class.
{quote}
Option 2 also looks correct to me.
