There is a problem with such tests in current framework. If you want to
test such things, you cannot rely on testing framework written in java.
You cannot check if 2+2==4 in same code which later compares this answer
with correct one and adds passed/failures together :)

Same goes for many other core features - if jvm needs testing for such
things, it is probable that it might break at any moment in unexpected
way. For such kind of stuff I think you should use testing framework
from other environment - bash/expect and fork separate jvm for every
test.

Mauve is core lib test, not jvm test and I believe it should focus and
stay on that subject. Nailing few jvm test on top of it won't help
anything. Full jvm testing is a subject for different project. And java
compiler testing is a subject for yet another one (in this case you
would need to have fully trusted jvm and fully trusted core lib). 

Just my $0.02.
