This tests what happens when class A extends abstract class B, but somebody
turns B into an interface without rebuilding A.

If you run this with --no-verify you get reasonable results:

java.lang.NoClassDefFoundError: Base
	at Main.main(Main.java:8)
	at dalvik.system.NativeStart.main(Native Method)
Caused by: java.lang.IncompatibleClassChangeError: superclass is an interface
	at dalvik.system.DexFile.defineClass(Native Method)
	at dalvik.system.DexFile.loadClass(DexFile.java:91)
	at dalvik.system.PathClassLoader.findClass(PathClassLoader.java:175)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:453)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:421)
	... 2 more

With the verifier enabled, you get a relatively content-free VerifyError
with the detail only appearing in the log file.
