I started developing Jessie so it could run on Sun's 1.2-1.4 runtimes,
as well as on Classpath-derived ones. At the time, there was a
divergence between Classpath and Java 1.4 in the Socket class (I don't
know if this is still the case) and you could configure the build
(with autoconf) to target Java 1.2, Classpath, or Java 1.4. In the
latter case, the commented stuff above would not be, and the exception
would.

I think I abandoned supporting Sun's runtimes, and just focused on
making Jessie work with Classpath. If Classpath is to the point where
the 1.4 methods are all present, then I should update the source to
reflect this.

In the meantime, I'd just suggest uncommenting those parts of those
methods. All the code to support Java 1.4 should be there, just
commented out.

Hope this helps.
