Bundling ASM in CXF

[Ian Roberts <i....@dcs.shef.ac.uk>]

I asked this a while ago, and I'll ask again: the ASM FAQ [1] recommends 
using the trick used by cglib-nodep of copying the particular version of 
the ASM classes that your code requires into your own package and 
bundling them in your JAR file.  Is there any reason (legal or otherwise 
[2]) why CXF couldn't do this?  It would solve the dependency hell at a 
stroke.

If the consensus is that it would be legal then I'm happy to try working 
on a patch.

This is actually very "easy" to do for the big bundled jar that we put  
by default in the lib dir.   The shade plugin that we use to create  
that bundle jar was specifically written for that purpose.   We just  
use the shade plugin to merge the jars together, but it does support  
the package/class mangling and such.   If you want to start looking  
into that, that would be great.

The trickier part would be to do it for the module jars and I'm  
probably going to suggest NOT doing it for them.   There are more than  
one modules that have ASM stuff in it (not just jaxws) and we probably  
don't want to shade it into a bunch of the jars.
