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

... 58 more 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..
