when parsing module ietf-ipv6-unicast-routing it contains some of the when statements like this:

when "derived-from-or-self(../../rt:address-family, "
       + "'v6ur:ipv6-unicast')" {

parsing this module gives me following error

which is saying that it can not parse XPath String because it doesn t know what rt is. We have this import in a yang file

  import ietf-routing {
    prefix "rt";
    description
      "An 'ietf-routing' module version that is compatible with
       the Network Management Datastore Architecture (NMDA)
       is required.";
  }

Weird thing is that this does not happen always. If I run test 10 times it will sometimes pass and most of the times fail.

When I tried to debug it I found out that interface YangNamespaceContextNamespace has following code

    static @NonNull YangNamespaceContext computeIfAbsent(final StmtContext<?, ?, ?> ctx) {
        final StmtContext<?, ?, ?> root = ctx.getRoot();
        YangNamespaceContext ret = root.getFromNamespace(YangNamespaceContextNamespace.class, Empty.getInstance());
        if (ret == null) {
            verify(ctx instanceof Mutable, "Cannot populate namespace context to %s", ctx);
            ret = new StmtNamespaceContext(ctx);
            ((Mutable<?, ?, ?>)ctx).addToNs(YangNamespaceContextNamespace.class, Empty.getInstance(), ret);
        }
        return ret;
    }

which sometimes returns YangNamespaceContext for module ietf-ipv6-unicast-routing with moduleToPrefix

{QNameModule@2999} "QNameModule{ns=urn:ietf:params:xml:ns:yang:ietf-inet-types, rev=2013-07-15}" -> inet
{QNameModule@3001} "QNameModule{ns=urn:ietf:params:xml:ns:yang:ietf-ip, rev=2018-02-22}" -> ip
{QNameModule@3003} "QNameModule{ns=urn:ietf:params:xml:ns:yang:ietf-interfaces, rev=2018-02-20}" -> if

this is when it failes and sometimes it returns only

{QNameModule@3008} "QNameModule{ns=urn:ietf:params:xml:ns:yang:ietf-inet-types, rev=2013-07-15}" -> inet
{QNameModule@3011} "QNameModule{ns=urn:ietf:params:xml:ns:yang:ietf-routing, rev=2018-03-13}" -> rt

where we have our rt and parsing will run fine..
