The latest versions of mapjfx – 1.22.0 and 2.3.0 – have the possibility to have different projections for the map used in OpenLayers. The possible projections are:

• Web Mercator (EPSG:3857); this is used if no other projection is specified and is the projection that was hardcoded up to now
• WGS84 (EPSG:4326); this can be set when initializing the MapView object.

Check the mapjfx-demo description and the source code. The actual versions are available in maven central:

  <dependency>
    <groupId>com.sothawo</groupId>

    <version>1.22.0</version>
