We've got a lot of code that uses @Override tags, and we need it to
compile under JDK 1.4. They cause compile errors. I'd rather not remove
the tags because they're really useful under 1.5.
Is there any way in Eclipse Preferences to temporarily ignore the
@Override tags when compiling under 1.4?

Wayne,
I think the .class file compatibility must be greater or equal to the
source compatibility... It would be nice if Java could compile 1.5
level source down to 1.4 compatible byte code...

Hi,
Well not at all if I read the document i referenced there appropiately
what the compiler does is simply adding casts inside the byte-code. This
could also be a pointer for our Java-5 discussion on the e4 mailinglist.

Thanks Ed. I was too lazy to try it myself; however, the properties let
you do this, so I thought it was worth a crack.
