[JBoss-dev] Version numbers in library filenames - Bad

I've seen a few cases where in repository.jboss.com the version number
for a library is included in the library filename,

E.g.
antlr-2.7.6.jar
addressing-1.0.jar
odmg-3.0.jar
quartz-all-1.5.2.jar
dtdparser121.jar
commons-lang-2.1.jar
myfaces-impl-1.1.3.jar

Even worse:
Cglib/2.1.0/lib/cglib.jar, cglib-2.1.1.jar

This is wrong, because
- whenever a library is updated we have to correct all explicit
references to it
- If you don't wipe your thirdparty on every update you may end up with
3 different versions of the same library and wonder for hours what's
wrong.

The version is encoded in the path and the library's
META-INF/MANIFEST.MF, not the filename, e.g:

apache-logging/1.0.3/lib/commons-logging.jar

For existing libs the harm is already done, but for new library
additions to repository.jboss.com, please have that in mind and remove
any version number from the filenames.

Thanks
