Notification does not allow leafref to enum

module IF-MIB {
yang-version 1;
namespace "urn:opendaylight:params:xml:ns:yang:nms:core:device-drivers:IF_MIB";
prefix "if-mib";

revision "2016-09-05"

{ description ""; }

container ifTable {
list ifEntry {
leaf ifAdminStatus {
type enumeration {
enum up

{ value 1; }

enum down

{ value 2; }

enum testing

{ value 3; }

}
}
}
}

notification linkDown {
leaf ifAdminStatus {
type leafref

{ path "/if-mib:ifTable/if-mib:ifEntry/if-mib:ifAdminStatus"; }

}
}
}

I am unable to generate java class for this yang model in version 1.1.0-SNAPSHOT. If I change notification keyword to containter for linkDown it's working, but with keyword notification I get this error message:

[ERROR] yang-to-sources: Unable to generate sources with org.opendaylight.yangtools.maven.sal.api.gen.plugin.CodeGeneratorImpl generator
