I am not on the latest and greatest I must admit :) And now you mention 
it I am not sure it is the same problem :)

Couple of things (maybe obvious, but you never know) :
- after a response.sendError(404) you should directly stop processing 
the jsp, so add a return after the sendError
- It could be that the response object is wrapped by opencms (if I am 
not mistaken it is). Try to get the original response and invoke a 
sendError on that object directly (if opencms actually override sendError)

Hope this helps :)
