Reflection is used for the super class constructor of BaseTest (ActivityInstrumentationTestCase2).

This also applies to UITest once bug 910859 lands.

sLauncherActivityClass should be made a member variable too (if possible).

Here's a try build that might achieve this: https://tbpl.mozilla.org/?tree=Try&rev=48c4ace2b5ab

The patches in bug 969922 (which are contained in the try build in comment 3) has resolved this issue. Nice work, Nick. :) There is still the reflection to obtain an instance of the class we're testing (i.e. `Class.forName(PreproccesedConstant)`), but considering we did not remove this from UITest, I take it it's a challenge. If you think it's worth trying, file a new bug for its removal from both BaseTest and UITest.
