Parser: XSD regular expressions are interpreted as Java regexes

I am using integration(stable/lithium), have registered a netconf device (device1) successfully.
When I try to mount the device it throws error as below :
http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes/node/device1/yang-ext:mount/
