[jsword-devel] Update on JSword

I think switching to Java 1.5 is a good decision.
As you said Java 1.5 is available for Mac OSX 10.4 and AFAIR this was  
the only door stopper.

Then it would also be nice to get Generics in JSword.

What actually is missing to bring JSword up to speed with C++ Sword?
I'd like to help out implementing some missing things when MacSword 2  
is finally released after a long time this week.
