I ran into the same issue when first looking at Antlr3. I was told the
intention was to not have the Antlr runtime rely on JDK 1.5; but
unfortunately some JDK 1.5 features ended up getting exposed.
The outcome of my queries, iirc, was that it would just remain JDK 1.5
compatible. You could probably use a retro-weaver though to make it 1.4
compatible. Did not try...
