No, currently libvirt-java does not support blockcopy.

Here's a breakdown of functions still missing from the Java wrapper
grouped by the libvirt version it has been introduced up to version
1.2.9 showing the coverage of each version.

Apparently, the virDomainBlockCopy function you're looking for was
introduced in libvirt 1.2.8 which is rather new. So, it's not very
surprising that it hasn't been wrapped up yet.

But, patches are welcome!
