Seems the runtime that is used doesn't support newer versions of class
file byte code (Unsupported major.minor version 48.0).
You are probably using a modern version of jikes that by default
generates this newer byte code. As far as I know all free runtimes in
main have been updated already to support it. But you can probably
downgrade the class byte code version used by giving jikes a -target 1.2
argument (see the jikes documentation).

Why? It isn't a bug with any of the free main runtimes. And it seems a 
upgrade of the non-free proprietary runtime that this person is using
would solve the issue.

If you really need to, why not create a new
libservlet2.3-java-nonfree-old-runtime package and keep the current
package in main since it seems to work fine with the free runtimes?
