I was able to find this example setting an enum on an annotation and have been looking through the code, but is there a way to do something similar referencing a static field? I've been looking through the RC1 source.

Code:
requestMappingAttributes.add(new EnumAttributeValue(new JavaSymbolName("namespace"), new EnumDetails(new JavaType("org.springframework.web.bind.annotation.RequestMethod"), new JavaSymbolName("GET"))));
