zoom level 19 and 20 in tms layer

[msreau@…]

I can't have zoom 19 and 20 in tms layer since the plugin slippymap was integrated into JOSM core

If I force the parameter with maxzoom level : 20 and min zoom level : 20 josm crash

I try wis this tms server : tms:http://tms.mapspot.ge/tms/2/nonstandard/{zoom}/{x}/{y}.jpeg (this area ​http://www.openstreetmap.org/?lat=47.4037742614746&lon=0.6427001953125&zoom=13 )

imagery.tms.max_zoom_lvl set to 20 and imagery.tms.min_zoom_lvl set to 15, I only get tile from zoom 15 to 18

imagery.tms.max_zoom_lvl set to 19 and imagery.tms.min_zoom_lvl set to 19, I get no tile

imagery.tms.max_zoom_lvl set to 20 and imagery.tms.min_zoom_lvl set to 19, I get no tile

imagery.tms.max_zoom_lvl set to 20 and imagery.tms.min_zoom_lvl set to 20, Josm crash with this message
