It would be possible (and easy) to create a specialization for the

Arrays.asList(a).subList), which would also fix the SOE problem
in this particular case.
It seems it would be a fairly clean win to no longer have Arrays.ArrayList
subclass AbstractList, getting rid of modCount (no structural modifications
are possible!), at the cost of more copying. Maybe it could subclass
AbstractCollection instead?
We can introduce an intermediate abstract base class for AbstractList,
which will implement a simpler version of sublists.
This BaseAbstractList could then be used for implementing
Arrays.ArrayList and Collections.SingletonList without paying too much
for copying code.
I wouldn't include such a change in this fix, however, and would leave
if for a separate enhancement.
