I created a patch to fix this issue.
First, it will not raise an exception anymore if the nodes are outside
the Lambert zones.
Second, it will display once an error message if someone tries to use
this Lambert projection beyond the latitudes it was designed for.
Third, I renamed the projection as Lambert Zone (France) to show
that this projection has limited coverage and is not for the whole
planet (I hope the new name is more clear).
If would be nice if someone with a write access could apply the patch
to the source Lambert.java.
I attach the patch with the extension .txt in this email but the patch
is also attached in the related Trac ticket 1441 :

Thank you in advance,
Pieren
