Well the problem isnt in Batik, the bug is in the FOP to Batik bridge code. 
Try running your SVG in squiggle to prove this.

I believe you are in luck. A very similar issue has already been reported in 
the following bug:

http://nagoya.apache.org/bugzilla/show_bug.cgi?id=24666

There is a patch you can apply to the source of the maintenance code 0.20.5 
and it may well fix the problem you are having with 6 digit coordinates. 
However, there are no guarantees, since the problem above is to do with 
transforms rather than actual coordinates, so it might not work. Worth a try 
either way.
