I need to run [JOSM][2] on Ubuntu.

Easies way seems to use [JNLP file][3], instead of downloading `.jar` file.

Ok, I know that is is Java Web Start, so I [lookup for `javaws`][1]. Which
gives me an `icedtea-netx` package.

```sh
sudo apt install icedtea-netx
```

Now it works perfectly fine on Ubuntu 16.04 LTS.

```sh
javaws https://josm.openstreetmap.de/download/josm.jnlp
```
