LGTM

So the only one type of dictionary that gains the super powers of resizing is the DelegatingClassLoader dictionary, but based on comments it's always size 1, so it never will need to be resized?

Related question, but not part of this fix - can we simplify things and not have to bother with 1 element dictionary for DelegatingClassLoader somehow?
