Restconf cannot deserialize leaf whose type is defined in another module

Define two yang models as follows

types.yang
==============

module types {
namespace
"urn:ping:params:xml:ns:yang:types";
prefix
"types";

description
"Types and Groupings";

revision 2014-07-05

{ description "Initial version."; }

typedef Name {
type string { length "1..64"; }
description
"This data type is used to model a name ";
}
}

test.yang
========

module test {
namespace
"urn:ping:params:xml:ns:yang:test";
prefix
"test";
import types { prefix "types"; }
description
"Test ";

revision 2014-07-05 { description "Initial version."; }

container test-container {
leaf test-name

{ type test:Name; }

}
}

Now try to set via restconf -
<test-container>
<test-name>Blah
</test-name>
<test-container>

org.opendaylight.yangtools.yang.binding.util.ClassLoaderUtils.loadClass fails with java.lang.ClassNotFoundException. This is because SAl is searching the package of "test" for "types" class.
