Checking out josm from git took at least 15 minutes, with the following
message:

Have you tried out the original svn-checkout? Would that be faster? At
least it would better reflect the version, as this is the SVN commit id.

I wonder where "jdk" comes in. I suppose it is some implicit (native?)
input from the ant-build-system. When I do a "guix gc --reference" I
see that it is referenced. Thus, it wouldn't be garbage-collected away
at least.

But wouldn't it be better to have the java-runtime (java:out) as an
explicit input and use that? Then it is first explicit and second would
use less space for people who do not need the full JDK. Though
sometimes programs NEED parts of the JDK, not only from the runtime. I
wonder if josm needs a JDK (usually these programs are more
server-oriented).

I found some files under LGPL (though not mentioned in the
REAMDE/LICENSE file :-)), like:

 ./src/org/openstreetmap/josm/gui/widgets/MultiSplitLayout.java

Looks like they are from Swing, I wonder if they are in any way
modified from the original ones.

While running the application:

I see a lot of NPEs on the console complaining about icons, though when
I run it, it looks good. I don't miss anything compared to my
downloaded josm-latest.jar.

When looking into the installed josm.jar, I find these:
24452 Tue Jan 01 00:00:00 CET 1980 images/presets/shop/kiosk.svg

But still having this error on the console:

Plugins: I will continue the discussions where I started.

Thanks again for getting that into Guix!
