[slf4j-dev] [OSGi] Manifests

[John E. Conlon]

Peter Kriens' Bnd tool for OSGi bundle creation is a very handy tool for 
creating and verifying bundles. 
See:  http://www.aqute.biz/Code/Bnd

I used it to verify our maven created jars and it reported a couple of 
errors with our OSGi metadata.  Here is an example of the output from 
the tool:

<Snip> $ bnd print

</Snip>

Would it cause anyone any pain if we removed the Bundle-Classpath from 
our manifests? 

kind regards,
