Bug#1100935: jython: interpreter stops with NoClassDefFoundError

[Bastian Germann]

Package: jython
Version: 2.7.3+repack1-1
Severity: grave
Justification: renders package unusable

Starting the jython interpreter fails since bookworm (where
libjline2-java moved from libjansi-java to libjansi1-java):

It is quite surprising that this has not yet been caught. Let's fix
trixie's jython or get rid of it.
