Summary

Introduce an option to disable dynamic resizing of system dictionaries during runtime.

Problem

https://bugs.openjdk.java.net/browse/JDK-8184765 introduces a new feature that will automatically resize a system dictionary if the load factor is determined to be too high. As a new feature there is a possibility that it might detrimentally affect performance of certain big apps.

Solution

Add a new, temporary, option "DynamicallyResizeSystemDictionaries" (default true) to allow users to disable the feature as needed.
