public class SkipShieldingInputStream extends FilterInputStream
skip(long) and delegates to FilterInputStream.read() instead.
Some implementations of InputStream implement InputStream.skip(long) in a way that throws an exception if the stream
is not seekable - System.in is known to behave
that way. For such a stream it is impossible to invoke skip at all
and you have to read from the stream (and discard the data read)
instead. Skipping is potentially much faster than reading so we do
want to invoke skip when possible. We provide this class so
you can wrap your own InputStream in it if you encounter
problems with skip throwing an excpetion.
