I am one of the grateful users of JDK1.1 support.  However, we are
being forced to "upgrade" to Java 2 because the 1.1 JVMs for Linux
no longer run on newer distributions (breaks beginning with RedHat 9,
for instance).  So I won't scream if dropping support streamlines
the design of Jython.

This is a shame, because the 1.1 JVM runs our multi user applications in less
than 1 meg of ram, and we run multiple JVMs for robustness.  With Java 2, the
same app runs in 24 megs of ram, and startup is quite a bit slower.  I don't
mind having lots of additional library classes available in case they
are needed, and don't mind a huge JVM distro due to big libraries.  But I hate
having to load them all at startup.

BTW, we run in classic mode to avoid even more ram use.  CPU is simply
not a problem for business applications.  Memory is.  We are ordering
servers with a minimum 1G ram to compensate, but this doesn't help
with slow startup.
