sun.misc.PerfCounter calls Perf.createLong with incorrect parameters

sun.misc.PerfCounter constructor calls Perf.createLong but it passes unit and varability in the 2nd and 3rd parameters which is incorrect. The signature of Perf.createLong is:
    public native ByteBuffer createLong(String name, int variability, int units, long value);

ByteBuffer bb = perf.createLong(name, type, U_None, 0L);
