>Description:
        From http://www.linuxfromscratch.org/blfs/view/stable/general/jdk.html
        Adding HOTSPOT_BUILD_JOBS=n to the port enables parallel multi-job building of the CPP part in jdk15. This decreases compilation time for hotspot VMs on a multi-cpu machine, even if it's a hyperthreaded one.
