Maybe a real concurrent problem:

OsbLayer is constructed org.openstreetmap.josm.plugins.osb.OsbDownloadLoop.run. Inside org.openstreetmap.josm.plugins.osb.OsbLayer is constructed. The constructor calls DataSet.selListeners.add. If this run at the same time as org.openstreetmap.josm.data.osm.DataSet.fireSelectionChanged this error might arraise.
