Per discussion in JBS, adds the following chars to the list of ignorable whitespace chars: U+000B (Vertical Tab), U+000C (Form Feed), U+0085 (Next Line), U+2028 (Line Separator), U+2029 (Paragraph Separator).
Adds the necessary testing in pre-existing automated test class `test/jdk/java/awt/font/TextLayout/FormatCharAdvanceTest.java`. Removes now-unnecessary manual test `test/jdk/java/awt/font/TextLayout/TestControls.java`. The `test/jdk/java/awt/font`, `test/jdk/java/awt/print` and `test/jdk/java/awt/Graphics2D/DrawString` tests all pass for me locally on Windows, Linux and macOS. ------------- Commit messages: - Add missing ignorable whitespace chars, add (automated) tests Changes: https://git.openjdk.org/jdk/pull/25560/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=25560&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8356803 Stats: 215 lines in 3 files changed: 40 ins; 161 del; 14 mod Patch: https://git.openjdk.org/jdk/pull/25560.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/25560/head:pull/25560 PR: https://git.openjdk.org/jdk/pull/25560
