Then, this is really a bug. If you have a little bit of time, would it=20
be possible to open a JIRA task with a small test case please?

Anyway, many thanks for yours report. It is a little bit mysterious why=20
it doesn't work for you since it work for me, but we probably have=20
different data (I have not tried yours code).

You can uses the 'zoom' field in ZoomPane (the MapPane ancestor) as below=
:

     point =3D zoom.inverseTransform(point, point);

It is not really the preferred way (this doesn't manage synchronization,=20
neither the mouse magnifier and stuff like that) but may be used as a=20
(deprecated!!!) work around.

The ZoomPane.zoom field is protected, because user are really not=20
supposed to access it directly. So you need to either turn it public, or=20
create a small sub-class of StyledMapPane in order to gets access to=20
this field.
