When I activated contourmerge plugin. ==== What is the expected result? The plugin should work. ==== What happens instead? 1. When I activated contourmerge plugin appears an error message. 2. Button of the plugin doesn't appear 3. If I restart JOSM with this plugin activated, JOSM doesn't start anymore (unless I delete the plugin from JOSM directory). ==== Please provide any additional information below. Attach a screenshot if possible. I tried delete ~/.josm directory, but the error persists. {{{ URL:http://josm.openstreetmap.de/svn/trunk Repository:UUID: 0c6e7542-c601-0410-84e7-c038aed88b3b Last:Changed Date: 2016-07-11 23:04:49
