such as %s, %d, %x... also width, left justify, zerofill flags are
implemented. Many of the other formats do not work, see the comments in
avian.FormatString javadoc and look for FIXME and TODO items for more
information on features that are known to not work correctly.
Rather than try to support mixing Avian's core classes with those of
an external class library -- which necessitates adding a lot of stub
methods which throw UnsupportedOperationExceptions, among other
comprimises -- we're looking to support such external class libraries
in their unmodified forms. The latter strategy has already proven
successful with OpenJDK's class library. Thus, this commit removes
the stub methods, etc., which not only cleans up the code but avoids
misleading application developers as to what classes and methods
Avian's built-in class library supports.
