Nit: It would be clearer to check for the specific metrics:

int[] cpusets = metrics.getEffectiveCpuSetCpus();
if (cpusets.length != 0) {

Same applies to getEffectiveCpuSetMems.  No need for a new webrev.

P.S. I am not sure the conversion from the primitive to boxed type
is necessary.  But this is not related to this issue.  You may
want to take a look at that.
