I plan to commit this in on Monday (so that I'm at the computer in case
something breaks) unless there are objections.
> Upgrade JUnit to 4.10, refactor state-machine of detecting setUp/tearDown
> call chaining.

> Both Lucene and Solr use JUnit 4.7. I suggest we move forward and upgrade to
> JUnit 4.10 which provides several infrastructural changes (serializable
> Description objects, class-level rules, various tweaks). JUnit 4.10 also
> changes (or fixes, depends how you look at it) the order in which
> @Before/@After hooks and @Rules are applied. This makes the old state-machine
> in LuceneTestCase fail (because the order is changed).
> I rewrote the state machine and used a different, I think simpler, although
> Uwe may disagree :), mechanism in which the hook methods setUp/ tearDown are
> still there, but they are empty at the top level and serve only to detect
> whether subclasses chain super.setUp/tearDown properly (if they override
> anything).
> In the long term, I would love to just get rid of public setup/teardown
> methods and make them private (so that they cannot be overriden or even seen
> by subclasses) but this will require changes to the runner itself.
