Rest annotations: Order @RequestParamter arbitrarily

[sleighsoft]

The following method results in a 'General Server error':
getFromPath(@RequestParam(value="var", required = false) String term_id, @RequestParam("anothervar") String anothervar)

This method does not result in an error:
getFromPath(@RequestParam("var") String term_id, @RequestParam(value = "anothervar", required = false) String anothervar)

Is it possible to allow arbitrary ordering of request parameters?
