There is no pair of character values in the latin1 range (0-255) that will make the condition at line 401 in `StringLatin1.java` true, so this test can be removed.
Added a test and a microbenchmark (which as expected sees a few ns/op improvement from this change). Took the opportunity to tune the default settings for the micro to reduce runtime from 30+ minutes to 3 with no discernible degradation of quality. ------------- Commit messages: - Add tests and micro - Simplify latin1 to latin1 locale-independent comparisons in StringLatin1.regionMatchesCI Changes: https://git.openjdk.java.net/jdk/pull/8292/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=8292&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8285001 Stats: 94 lines in 3 files changed: 88 ins; 3 del; 3 mod Patch: https://git.openjdk.java.net/jdk/pull/8292.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/8292/head:pull/8292 PR: https://git.openjdk.java.net/jdk/pull/8292
