I am not sure about the files you have attatched.  They show a JDT editor error which is unrelated to Snippet212.

When I follow the steps in your description, I get the following error:

Yes, that's the problem, you got it.

I really don't know bugzilla will show my input as a link, so please don't bother with them.
