The same version string is available from both APIs, reading from the SystemVersion.plist is a bit slower. It would be clearer to move the checking of SYSTEM_VERSION_COMPAT to the first test (line:252) so the version info does not need to be read from the files. - PR: https://git.openjdk.java.net/jdk/pull/2530

FWIW, it seems to work OK using the legacy fallback path (reports 10.16 if I set `SYSTEM_VERSION_COMPAT=1`). - PR: https://git.openjdk.java.net/jdk/pull/2530
