Well having to deal with quite a few embedded hardware devices with java
console apps which work in JDK 7 for FC19 but not JDK7 for FC20... one
should never ever assume that some other programmer hasn't found a way to
break Java's compatibility. I would say that there needs to be something a
bit larger than a rebuild but a mass test so that you end up with finding
out that someone's hack to make java-7 do something neat isn't java-8
runtime saying 'crash'.
