OperatingSystemMXBean was changed in jdk14 (see JDK-8226575): New methods getTotalMemorySize and getFreeMemorySize were added, old getTotalPhysicalMemorySize and getFreePhysicalMemorySize were deprecated.
The fix adds fallbacks for the values (i.e. if new methods fail, jconsole calls old methods) ------------- Commit messages: - Adds fallback getters Changes: https://git.openjdk.java.net/jdk/pull/1243/files Webrev: https://webrevs.openjdk.java.net/?repo=jdk&pr=1243&range=00 Issue: https://bugs.openjdk.java.net/browse/JDK-8255934 Stats: 22 lines in 1 file changed: 20 ins; 0 del; 2 mod Patch: https://git.openjdk.java.net/jdk/pull/1243.diff Fetch: git fetch https://git.openjdk.java.net/jdk pull/1243/head:pull/1243 PR: https://git.openjdk.java.net/jdk/pull/1243
