This is *very old* version of Java which is no longer supported. In
fact, Jack installation pages explicitly say that you need Java 1.0.2
or higher for Jack (now called JavaCC) to run.

We want to support both JDK1.0.2 and JDK1.1, due to which you get
those warnings. The problem with fixing these is that their
replacements are not upward compatible, so people still using 1.0.2
will have trouble. Once JDK1.1 becomes the official release of Java,
we will also switch to 1.1.

The problem here is that you are using an old version of Jack. There
is a new interim version which is being tested by users on the
jack-interest mailing list.


Very soon (by the end of the week), we will be announcing the Beta
release of JavaCC0.6 on all relevant NGs. So stay tuned. If you are in
a hurry and want the early release, please send mail to
jack-help@asap.eng.sun.com.
