I added a call to kawa.standard.Scheme:registerEnvironment.  Now it goes
a bit further until defineClass fails:

gnu.text.SyntaxException: 
<unknown>: internal compile error - caught java.lang.UnsupportedOperationException: can't load this type of class file
    java.lang.VMClassLoader.defineClass(Native Method)
    java.lang.ClassLoader.defineClass(ClassLoader.java:319)
    java.lang.ClassLoader.defineClass(ClassLoader.java:283)
    gnu.bytecode.ArrayClassLoader.loadClass(ArrayClassLoader.java:134)
...

the android-defs module should probably call registerEnvironment
automatically.
