I'll test this here and apply.  Thanks for spotting.  I did wonder
about this when I made the change, so probably should have tested
myself.

The 1.6 changes are from Lillian's patch to the icedtea tree and I agree
they seem unnecessary to me.  Lillian, why was this needed? If there is
no good reason, I'm in favour of going back to 1.5.  1.6 does seem to work
with ecj on Debian so far (may have to contradict that later though),
so I don't know what Fedora 8 uses to build.

Indeed, @Override is one of the 1.5 to 1.6 changes, but this only
occurs in OpenJDK b25 or b26 and later.
-source 1.6 will only fix it with a very new ecj -- see my other post.

Thanks!

Sounds good to me.
