I am working wth Alexandre Porcelli on some major changes to the HQL
translators.  Since the changes are drastic we decided to move from
Antlr2 to Antlr3 in the process as Antlr3 offers many benefits over

The only concern I have with the move to Antlr3 is the fact that Antlr3
only works with JDK 1.5+.  I had planned on incorporating this work into
Hibernate 3.5.  The obvious question being the corresponding JDK move
for Hibernate users migrating to 3.5.

Anyone have strong reasons to not do this move in the 3.5 timeframe?
