Description
This initial implementation includes work that covers the following subtasks: JDK-8133975 add hashing implementation to unmodifiable sets and maps JDK-8133979 make all unmodifiable List implementions implement RandomAccess JDK-8133976 add random iteration order to hash-based unmodifiable collections JDK-8133980 reuse emptySet, singletonSet, etc. for various views such as entrySet() on one-element Map JDK-8139231 tune unmodifiable implementations based on size and performance test results I'll therefore close out those subtasks as duplicates of this one.
