I don't know what to say.  Finding consensus is part of The Apache
Way.  I guess this means all concerned parties should try and be
reasonable and remember that this is a do-ocracy.  If Seb wants to
make the contributions that will keep [jexl] 3x compatible with 1.5, I
don't see that this should inconvenience Henri B. to the point that he
should rather work elsewhere.  Again, when the burden of maintaining
compatibility becomes too great, it will be obviously time to move to
Java 6.

On the other hand, how long will an API redesign take?  Maybe the
right approach is to start with Java 6, then whoever likes to can
investigate how much work it would take to restore Java 5
compatibility.  This could even be done with multiple mvn modules.
