This fixes a few memleaks and other errors.
Note, that the memleak patches depend on the error refactoring
patches I posted to this list[1]
[1] https://www.redhat.com/archives/libvir-list/2014-January/msg00415.html
Claudio Bley (10):
Implement equals and hashCode methods for Connect and Domain
Fix warnings using raw types
Fix warnings about accessing static methods
Remove unused fields of Error class
Fix Domain.getSchedulerParameters / getSchedulerType
Fix memleak in Domain.snapshotListNames
Fix memleak in StoragePool.listVolumes
Fix memleak in DomainSnapshot.getXMLDesc
Fix memleak in StorageVol.getPath
Fix memleak in StorageVol.getXMLDesc

The getSchedulerType method returns a String (the name of the

It's OK to just pass null for the second argument to
virDomainGetSchedulerType.
Ensure to free the returned string.
