      Description

        The reason why PER_CPU_SHARES has been abstracted in the JVM to 1024 seems somewhat arbitrary. It resulted in this thread being raised:

        http://mail.openjdk.java.net/pipermail/hotspot-dev/2019-January/036087.html

        A bit of rationale should be added to the code to explain this situation.
