### Motivation Optimize concurrent collection's shrink and clear logic. This PR was releated to bookkeeper's PR：https://github.com/apache/bookkeeper/pull/3417 ### Modifications 1. Reduce the repeated `Arrays.fill` in the clear process 2. When `capacity` is already equal to `initCapacity`,`rehash` should not be executed 3. Reduce the `rehash` logic in the `clear` process 4. Shrinking must at least ensure `initCapacity`, so as to avoid frequent shrinking and expansion near `initCapacity`, frequent shrinking and expansion, additionally opened `arrays` will consume more memory and affect GC. ### Documentation Need to update docs? - [x] `doc-not-needed` -- This is an automated message from the Apache Git Service.
