SLSLogger is broken when used with with `System.Logger` (-Djavax.net.debug mode)
SSL Debug messages don't use format specifiers. As a result, any custom format data isn't printed. Proposed solution is to append the SSL custom format output to the original debug message. Similar approach used for `SSLConsoleLogger ` mode. Used this opportunity to delete some old commented code and to replace use of `"\n"` with `System.lineSeparator()` DebugPropertyValuesTest also updated to test new logic. ------------- Commit messages: - 8343395 Changes: https://git.openjdk.org/jdk/pull/25934/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=25934&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8343395 Stats: 28 lines in 2 files changed: 7 ins; 10 del; 11 mod Patch: https://git.openjdk.org/jdk/pull/25934.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/25934/head:pull/25934 PR: https://git.openjdk.org/jdk/pull/25934
