[libvirt] Release 0.4.1 of libvirt-java

[frederic.dangtran at orange-ftgroup.com]

Yes it works. No longer any NPE when I invoke getSchedulerParameters() on a Xen domain: I can retrieve both  the scheduling cap and weight.
I guess the problem pops up only when there are more than 1 sched parameter to return  with the unmarshalling of the second one going wrong.
