I still have to write a test case.

Yes, the testcase needs to simulate a large number of (about 60189 - 49191) classes just like import javafx modular.

Thanks, Leslie Zhai

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?

[coleenp]

Thanks for the reviews, Ioi, Calvin and Gerard. To answer your question about the DelegatingClassLoader - it's always a 1 element hashtable so would never need to be resized. Seems efficient to specify a very small hashtable. We may be able to eventually remove it because of JEP 416: JDK-8271820. Thanks. /integrate
