SVGLocatable.getBBox(elem) returns null No javadoc comments are there to
unveil the reason of such behaviour
Is there the other way to get coordinates of SVGOMGElement ?

I use batik to operate SVG at runtime.
The question is how can I get SVGOMGElement coordinates when walking DOM
tree of the SVG document?
You should look at the SVG DOM. In particular the 'getBBox' method.
There are also methods get 'getIntersectionList' that could be useful.
The reason I'm asking such a thing it that requirements are to display
info popup near named elements of SVG. If I had coordinates of such an
element I could use DOM to add new element to the tree with computed
coordinates for correct positioning of the info popup.
This is typically done with mouse over/out event handlers. This
allows you to receive a DOM event when the mouse enters/exits a particular
element or group in the SVG document. If you need the sensitive area to
be larger than the rendered area you can add a hidden element
(visibility="hidden" pointer-events="fill") that can cover the expanded
area and tie your event handler to that.
