It's a bug, things should be evaluated in their original coordinate system,
but
it's quite a hard one to fix.
Labels are done last, when all the geometries are already turned into
screen space,
making the label be computed first will require changes in more than one
class
back in GeoTools.
Please open a ticket on jira.codehaus.org, but be also ready to fix it
yourself
if you need the fix quickly
Cheers
