OK, I remember, we were talking about on dev list last week. At first glance, body parameter would seem unnecessary, so I think is a good candidate for removal, though it don't cause any side effect (except for the exception in debug mode). So, my suggestion is file a issue on JIRA [1]. I attached submit.ftl file. You could publish in your WEB-INF/classes/template/simple/submit.ftl (or whatever is your classpath dir) while waiting for patch.
