What steps will reproduce the problem?

1. Install Opendata plugin. This will install some dependencies, including Geotools
2. Restart JOSM

What is the expected result?

To have the Opendata plugin (including the Geotools plugin)

What happens instead?

Please provide any additional information below. Attach a screenshot if possible.

I have tried to remove all JOSM configuration files and started with a fresh installation. This did not help.
