Can you dig down and make sure which JVM you have running JOSM, and also
figure out which packages you are using?

You can do it like this:

dave at nimitz:~$ ps aux | grep josm
dave     17100 16.9  7.2 1445780 289108 pts/28 Sl+  14:29   0:19 /usr/lib/jvm/java-6-openjdk/jre/bin/java -jar /home/dave/projects/osm/svn.openstreetmap.org/applications/editors/josm/core/dist/josm-custom.jar -Xms1500M -Xmx2048M --no-fullscreen /home/dave/projects/osm/work.osm
...

That'll give you JOSM's pid, which you can dig into the rest of the
information with.

dave at nimitz:~$ ls -l /proc/17100/
total 0
-r--------  1 dave dave 0 2009-10-13 14:31 auxv
-r--r--r--  1 dave dave 0 2009-10-13 14:31 cgroup
--w-------  1 dave dave 0 2009-10-13 14:31 clear_refs
-r--r--r--  1 dave dave 0 2009-10-13 14:30 cmdline
-rw-r--r--  1 dave dave 0 2009-10-13 14:31 coredump_filter
lrwxrwxrwx  1 dave dave 0 2009-10-13 14:31 cwd -> /home/dave/projects/osm/svn.openstreetmap.org/applications/viewer/jmapviewer
-r--------  1 dave dave 0 2009-10-13 14:31 environ
lrwxrwxrwx  1 dave dave 0 2009-10-13 14:29 exe -> /usr/lib/jvm/java-6-openjdk/jre/bin/java
...

Then you know which jvm you are using.  If this doesn't work, you can
also:

	cat /proc/17100/maps

Then:

$ dpkg -S /usr/lib/jvm/java-6-openjdk/jre/bin/java
openjdk-6-jre-headless: /usr/lib/jvm/java-6-openjdk/jre/bin/java
$ dpkg -l | grep openjdk-6-jre-headless
ii  openjdk-6-jre-headless                     6b14-1.4.1-0ubuntu11                      OpenJDK Java runtime, using Hotspot JIT (headless)
$ apt-cache show openjdk-6-jre-headless
Package: openjdk-6-jre-headless

Section: interpreters
Installed-Size: 73008
Maintainer: Ubuntu Core Developers <ubuntu-devel-discuss at lists.ubuntu.com>

...

Make sure that if you get a different package name than
"openjdk-6-jre-headless" that you substitute it in the subsequent
commands.
