RFR 8058575: IllegalAccessError trying to access package-private class from VM anonymous class

Thank you for looking at this change.
Not allowing host classes to be array classes is not completely
unrelated to this bug because it affects the implementation of the code
that prepends the host class's package to the anonymous class.
We decided to not allow array host classes in JDK-9 because it makes no
sense. A user who does this is likely doing so in error, and should be
flagged for it.
We recognize that this, and many other things, will have to change once
array classes have their own methods.
