Scanning has a huge impact on startup performance and a brief impact on memory.

The way the EE specs are written we have to scan all jars "just in case" they might have a
class with @Stateless or @ManagedBean or @WebServlet, etc.  But if you know which jars are
your code and which are third-party libs, you can get a tremendous boost letting us know via
the scan.xml file.

List the jars where your code lives via the scan.xml file and things will be quite snappy
on startup.
