If the plugin is disabled, everything works as expected.

If the plugin is updated, everything works as expected. Current version is 33088.

[cmuelle8]

This was a weird problem:

Everytime plugins were updated josm was fetching 33088,
but after a restart reverted to 32804.

Turns out an ubuntu packaged version was installed as well,
and there is also a package in wily called "josm-plugins".

System plugin path had version 32804, which is why it was
not useful to remove them from ~/.josm/plugins.

If there are plugins under /usr/share/josm/plugins
they are prefered over the ones in ~/.josm/plugins
_even if_ the plugin version in the latter is newer.

The system copy was removed by issuing

sudo apt-get remove josm josm-plugins

which removed the following files among others:

​http://packages.ubuntu.com/yakkety/all/josm-plugins/filelist

While it does solve the problem (version 32048 is not prefered
over 33088 anymore), it should be handled differently imho.

-> If the user downloads a plugin to his home directory,
it should be prefered over the ones in the system path.
Afaik, this is common policy for pretty much all settings
in unix/linux.

Closed as duplicate of #7483.
Problem known for years, the package has been simply deleted recently.
