> Using a class constant (static final field) in an annotation causes compile errors.  This works in Java and the fix is pretty small.
> Ex:
>             class C {
>               public static final String VALUE = 'rawtypes'
>               @SuppressWarnings(VALUE)
>               def method() {
>               }
>             }
> This is a bit contrived to be concise.  But we have examples in our code where Callable impls are tagged with a name, which is defined as a static constant on each class.
> The fix appears to be pretty minor.  In ResolveVisitor.transformInlineConstants, a case for VariableExpression does the trick for me.
>         } else if (exp instanceof VariableExpression) {
>             VariableExpression ve = (VariableExpression) exp;
>             if (ve.getAccessedVariable() instanceof FieldNode) {
>                 FieldNode fn = (FieldNode) ve.getAccessedVariable();
>                 if (!fn.isEnum() && fn.isStatic() && fn.isFinal() &&
>                         fn.getInitialValueExpression() instanceof ConstantExpression) {
>                     return fn.getInitialValueExpression();
>                 }
>             }
