Hi Gavin,

Yes, the ambiguity here is unfortunate.

The code currently (and at both the 1.5.3 and 1.5.5 tags) accepts any
number of leading \r and \n characters before a command -- what exactly
does the STOMP adapter do when it is sent a \0\n sequence as a frame
terminator?

Yes, that's a current problem. I'll fix that in a similar way to the way
excess \n's are (or at least *should be* :-) ) being ignored now.

Yes. I agree. I think it should, however, stay strict in terms of what
it emits (i.e. continue to use plain \0 for its frame terminator when
it's speaking) -- do you think that makes sense?
