I'm not sure why you are getting a CNFE for java.lang.System...that
seems really odd.
However, the fact that you cannot resolve your bundle may be legitimate,
since you are creating a command for the old Felix Shell service, but it
looks like you are running the 3.0.x framework distribution that now
uses Gogo.
Gogo doesn't have a lot of documentation yet, but we do have some
rudimentary documentation on how to create commands for it. It is
actually easier than the old approach:
http://felix.apache.org/site/rfc-147-overview.html
You can also look at the source code for the Gogo Command bundle, which
provides the best example:
http://svn.apache.org/repos/asf/felix/trunk/gogo/command/

I am in the process of learning OSGI and I am attempting to write a
simple felix shell command which tells me if a word is spelled
correctly or not (using the examples as a starting point) but I'm
running into problems. My manifest looks like this,

Bundle-Name: Service listener example

I've tried tweaking the version numbers in the manifest in every way I
can think of but I continue to get the following error,
