Fix WinL10nTest test to use proper l10n string for picking up WiX version from jpackage output when it is invoked as a command and not as a tool provider. As a supplementary change, refactored test cases initialization.
The fix revealed a couple of issues in how the CommandOutputControl class handles encoding when saving the output of executed commands. All issues fixed with additional unit tests added to cover changes. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - CommandOutputControl: encoding bugfix - 8386609: WinL10nTest.java does not respect locale for WixType Changes: https://git.openjdk.org/jdk/pull/31543/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=31543&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8386609 Stats: 208 lines in 4 files changed: 99 ins; 19 del; 90 mod Patch: https://git.openjdk.org/jdk/pull/31543.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31543/head:pull/31543 PR: https://git.openjdk.org/jdk/pull/31543
