Our historical preference for compile-time type errors gives rise to code like

if (UIManager.getLookAndFeel() instanceof WindowsLookAndFeel)

[Various other packages snipped]

Like I said, we will get around to rewriting what absolutely needs to be tweaked where we can, but being able to use the escape hatch like a command-line app (along with fixes for 8152838 and 8152839) will allow us to continue our testing.
