I think that this is the killer.

If you don't want to treat some classes as black boxes (and I think that
this would, in fact, break the correctness of the analysis), you can also
use a simplified classpath.  Some of the classes in Java's classpath are
more complicated than they actually have to be to run benchmarks (cough,
cough).  Perhaps GNU ClassPath might be more amenable to analysis, if it
can run your benchmarks properly.

Alternately, you can provide simplified implementations of various core
classes.  I'm not sure how well this would work.  And it requires some
programming.
