Currently if loading a core file fails, the diagnostic information provided on different systems is different; on MacOS we produce an error message, while on Linux we only print information if debug logging is enabled.
This PR adds some new messages on Linux to match MacOSX, and changes some of the diagnostic output to error level instead of debug. Additionally, if opening the core or the exe file fails, the system error message (strerror) is printed. Tier1-3 testing clean. ------------- Commit messages: - Update copyright - Report more information on error Changes: https://git.openjdk.org/jdk/pull/24722/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24722&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8354920 Stats: 21 lines in 2 files changed: 8 ins; 0 del; 13 mod Patch: https://git.openjdk.org/jdk/pull/24722.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24722/head:pull/24722 PR: https://git.openjdk.org/jdk/pull/24722
