Used to use -package to specify the base package name and then JspC would
assume that the directory structure of your JSPs was the fully qualified
package name: bold assumption on the surface but that's what the appservers
expected as well. Now the -package is used on every JSP in the tree you
point at using -webapp - calling the JspC compiler with a java fork from ant
versus built-in ant task with an unknown vintage of Jasper. Seems like a bug
but then perhaps assuming directories were sub-packages was deemed to
presumptive.
