I tested this, and get the following behavior on macOS 11.0.1 with a JDK compiled with Xcode 11.3.1 and your patch: SYSTEM_VERSION_COMPAT not set : 11.0 SYSTEM_VERSION_COMPAT=1 : 10.16 SYSTEM_VERSION_COMPAT=0 : 11.0.1 So the fallback path reports what could be considered a more accurate version, at least on my laptop. Since I'm not sure what is expected, you can decide what to do with this information. ------------- PR: https://git.openjdk.java.net/jdk/pull/2530
