Hi Ivanhoe - I just cleared my Maven repo, checked out and rebuilt
Aries, ran the blog sample and it failed. Thanks for highlighting this -
it is not something you are doing wrong. We'll fix it.

Hi Lin/Jeremy.
Ok I understand that the empty files should not pose a problem.
However I am still not able to run the blog sample.
I tried your (Jeremy) suggestions.
I removed the org.apache.aries bundles from my local .m2 repository,
and then built again (mvn -fn clean install).
I then tried the sample again but with the same results.
My envirionment
Ubuntu
jre1.6
I checked out Aries trunk (my eclipse svn-plugin reports revision
944137) using the eclipse m2 plugin
So I am not sure why I am getting different results than you guys. I
will try at home as well. There I have an old windows setup.

Hi Ivanhoe, I'd agree with Jeremy that these empty files should not
get you the CNFE you hit. In ARIES-272, we switched to use the
RecursiveBundleTracker instead to better keep track of bundle events.
Anyway, let us know if you still hit this prob and how we can recreate
it (with which revision).
Thanks
Lin
