properties layer & wms layer IllegalArgumentException while trying to add WMS-Layer

[fgdrf]

What I did in uDig:

• added a properties file as layer (DataStore -> Properties -> Select a Folder where a properties files exists) (see cities.properties from https://docs.geotools.org/stable/userguide/library/render/chart.html)
• add GeoServer WMS layer from demo page (http://udig.github.io/data/demo_servers.html)

Than this error was logged and displayed in error-log view:

Can you describe what you actually did to get this stacktrace? The title is a hint only (for me).

Updated issue details ;) So you have some data-sets you can test with
