Please review this change for the `jar` tool to gracefully handle the case where `--release` is not specified as the last arguments.
Prior to this commit, operation modes `-d --describe-module` and `--validate` expected to read the optional `--release` option as a file argument: `jar -d -f a.jar --release 9` By adding a hidden GNU-style `--release` option, processing the optional arguments before in those two operation modes, the position is now no longer required to trail behind the `-f --file` option: `jar -d --release 9 -f a.jar` ------------- Commit messages: - 8316804: Gracefully handle the case where --release is not specified last Changes: https://git.openjdk.org/jdk/pull/22079/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=22079&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8316804 Stats: 45 lines in 2 files changed: 35 ins; 3 del; 7 mod Patch: https://git.openjdk.org/jdk/pull/22079.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/22079/head:pull/22079 PR: https://git.openjdk.org/jdk/pull/22079
