The "1.1" doclet was introduced to provide a transition path
from JDK 1.1 Javadoc to SDK 1.2 javadoc. This transition
is long past. The "1.1" doclet does not handle new features
of the language (such as inner classes) and because of shared
code with the standard doclet is an impediment to maintenance.
Remove the doclet and the "-1.1" option from the javadoc tool.
