I'm aware of the fact that this is a bit unfortunate but I don't want to
remove the dependency on java2-runtime because for example SUN's java
provides this and josm of course works fine with it. It's also a
requirement by the Java policy which is a bit controversial to the fact
that a package "must specify the dependency information about other
packages that are required for the first to work correctly".
Josm simply does not work with every java implementation which we try to
address in the wrapper script that ignores the alternatives system and
trys to find a working jvm instead. If none is found it gives hints how
to resolve this.

Because it's very likely that /usr/bin/java points to a jvm that does
not work. This would just show an empty GUI interface without any hints
for the user about what possibly went wrong.
See also #474626 and #472285.

I agree that the dependency can be tightened to depend on
gij-4.1 | jamvm | java2-runtime instead of java-gcj-compat (which is
again just a meta package) until the bug is fixed that prevents josm to
work with the version provided by java-gcj-compat.
But this still cannot prevent installations where a working jvm is
