Re: problem in using spi fly (strange exceptions...)

[David Bosschaert <da...@gmail.com>]

Just to follow up on this on the list.
Oliver and I have been working on this over the past while. His
use-case uncovered a number of new scenarios and issues (e.g. [1])
that I have since fixed on spi-fly trunk.

I've also improved the documentation:
http://aries.apache.org/modusles/spi-fly.html

Best regards,

David
