        Description

        when running jdk9, inside an ldom, where the ldom was created with
        ldm set-domain cpu-arch=generic
        or cpu-arch=migration-class1

        the kstat info for the cpu type is set to sun4v-cpu, which java does not know about.

        ./java
        Java HotSpot(TM) 64-Bit Server VM warning: Can't parse CPU implementation = 'SUN4V-CPU', assume generic SPARC
        # To suppress the following error report, specify this argument
        # after -XX: or in .hotspotrc: SuppressErrorAt=/vm_version_sparc.cpp:433
        #
        # A fatal error has been detected by the Java Runtime Environment:
        #
        # Internal Error (/u01/andyb/jdk9/hotspot/src/cpu/sparc/vm/vm_version_sparc.cpp:433), pid=2248, tid=2
        # assert(is_T_family(features) == is_niagara(features)) failed: Niagara should be T series

        the platform is actually a T4
