Giovanni Matteo Fumarola commented on HDDS-818:
-----------------------------------------------
I attached a potential fix.
Since 2 classes have the same XmlRootElement, the system does not know which
class should use for the decode the XML response.
How to reproduce? Using any REST client tool call ws/v1/cluster/scheduler-conf
from select XML as return format.
