Summary: Crash when creating a class in an illegal package

Initial Comment:
DynamicJava allows classes to be created in arbitrary packages, but doesn't cleanly handle errors when adding to a package is not allowed.  Example:

> package misc;
> class Foo {}
> Foo.class
class misc.Foo
> package java.lang;
> class Mom {}
> Mom.class
[error occurs]
