`ByteArray` and `ByteArrayLittleEndian` are very useful tool classes that can be used in many places to performance tuning.
Currently they are implemented by `VarHandle`, so using them may have some impact on startup time. This PR reimplements them using `Unsafe`, which reduces the impact on startup time. ------------- Commit messages: - use Preconditions.AIOOBE_FORMATTER - delete extraneous whitespace - delete extraneous whitespace - get/set unsigned int - Reimplement ByteArray and ByteArrayLittleEndian with Unsafe Changes: https://git.openjdk.org/jdk/pull/14636/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14636&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8310843 Stats: 268 lines in 2 files changed: 135 ins; 64 del; 69 mod Patch: https://git.openjdk.org/jdk/pull/14636.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14636/head:pull/14636 PR: https://git.openjdk.org/jdk/pull/14636
