22057	[Patch]ClassNotFoundException when installing a plugin that was already downloaded	Emvee	team	"I suddenly lost my ~/.config/JOSM/preferences.xml (also the backup) so I had to reconfigure Josm.

One of the plugins I use often is utilsplugins2 but installing that pops up a warning:

Could not load plugin 'utilsplugins2' because the plugin main class 'org.openstreetmap.josm.plugins.utilsplugin2.UtilsPlugin2' was not found. Delete from preferences?

The the choice ""Disable plugin"" or ""Keep plugin"" is given and I did chose ""Keep plugin"".

After a restart I see the settings menu got a ""Utilplugin2 settings"" menu and there I can edit the ""Custom URL settings"". I see also the additional tools under ""More tools"" so that all seems to work.

First the added shortcut keys (Ctrl-H, Ctrl-T etc.) did not work but after some more testing that did also work.

So I see no problems yet with the operation, still I do not like this ""Disable plugin"" when installing the plugin. I have tried 3 times reinstalling the plugin and could every time reproduce the problem
