Re: [cilib-devel] Bug in next branch: class PartialReinitialisationResponseStrategy

[Gary P. <gpa...@gm...>]

Thanks for the heads up Andrich. A good catch.

next has not been merged into master yet (thankfully). I will *NOT* be merging 
it until I receive a patch for the offending class. Code that is in that state 
will not make it into a release.

Please get the patch to me asap. This would have obviously been found if there 
were some unit tests for the class. Wasting time like this is not 
constructive, at all.
