What steps will reproduce the problem?

What happens instead?

==> a separate window appears with the information (in german)

(nonexpected exception)

As the error message says: You're using a plugin (JosmReviewPlugin) which isn't compatible to your Java version.

That's very likely an error in the plugin which doesn't correctly state the Java version it needs.

Please report the issue here (​https://github.com/DavidKarlas/JosmReviewPlugin) and maybe also tell the author that his name is encoded wrong in the manifest.

The easiest way to workaround is to update Java version or to delete the plugin.
