My guess is that it's a bug. *Probably* the null pointer exception is in TearDownFixture, which (I'm guessing) has not had isisJdoSupport injected into it.
If you run this fixture from an instance of FixtureScripts service (ie in the app), I suspect it will work. That's because the FixtureScripts infrastructure automatically injects instances into any subfixtures (eg TearDownFixture). But possibly this isn't happening correctly if (as you are doing) the fixture is registered in isis.properties using the isis.fixtures key. I'll look into a bit more this evening.
