This will be fixed as soon as 9795 will become a stable build.

You can (and normally should) distribute different versions of the plugin depending on the JOSM version. See DevelopersGuide/DevelopingPlugins on Plugin-Url entries in the Manifest. E.g. ​scripting-plugin is a good example of a plugin using this mechanism.

As said in e-mail this is kind of easter and egg problem, we try to ensure via unit tests that all plugins are working fine before we release a new stable version.

In 9815/josm:

see #12514, see #12533 - fix/ignore longstanding problems in unit tests

Solved in scoutsigns version 73.
