Simple use normal if/then. Java VM will recompile it at runtime. This probably 
wont work in java5 if compiled for java6 :-(

This solution should work better

I personnaly dont want any complications in running josm from sources. 
Developing should be easy and not hard to start.

About to cut 1.5 support. I hope that josm users (whole osm comunity) is so 
advanced PC/MAC users that this switch wouldnt be problem. Running in virtual 
machine, on remonte server with X server isntaled or so.

I give one small point to cutt 1.5 support. Maybe we should give some pool to 
web page or to user mailing list. Result of pool shouldn be just "yes=2222, 
no=322, dontKnow=33" but arguments/reasons why no. (we know why yes :)

Have a nice day.
