It's just ecj.  ecj comes out with millions of warnings.

Basically, it's the compiler saying "I don't like your coding style.
Please try to be a better programmer and I'll shut up."  I think the
compiler should just STFU anyway and get on with its job.

The Sun javac equivalent for ecj's default is -Xlint, in which case it
emits nearly as many warnings as ecj.  But this only happens if you increase
the maximum warning count; otherwise it just prints the first 100 warnings.

I don't know why IBM chose to make warnings=on the default, unlike Sun
and just about every other compiler provider.  But Sun still prints a
few really useful warnings, even without -Xlint.

I don't think there is an ecj equivalent of Sun's default.
Now that we've got a separate ecj RPM we could provide one.
