Yes. We removed a patch in Rawhide that was diverging from upstream. Now
Fedora's OpenJDK 8 is more like upstream OpenJDK 8 and (proprietary)
Oracle Java 8.

Yup. This patch was *disabling* doclint. Now it is enabled by default.
This makes javadoc much more strict about what is validates as valid
javadoc. If your javadoc is invalid for some reason (bad html, unescaped
entities, adding comments after @return), then javadoc will now fail.
There's more information about this, including more details about how to
turn it off, here:
http://blog.joda.org/2014/02/turning-off-doclint-in-jdk-8-javadoc.html
TLDR: You can disable doclint by passing the `-Xdoclint:none` option to
javadoc.
Another option is to fix the upstream package to have valid javadocs and
contribute the fixes back upstream. They will hit the same issues when
they try building using the (proprietary) Oracle Java 8. This will fix
it for others too.

Yeah, it's a bit too strict, IMHO. But upstream is unconvinced at this
point about it. Fortunately, fixing the javadoc is quite simple,
generally. If anyone needs help, I will be happy to do what I can to fix
packages.
Thanks,
