Yang-UI hangs - 'Loading modules from controller - Processing modules'


Lyle
 

Upon rebuilding of a plugin on 6/17 (beryllium) after over a month (last build was 5/2)  my project hangs in the YangUI with the 'processing modules'  statement.

Via command line (curl scripts) I can verify that RESTCONF is functioning.

In the karaf log I see numerous errors of the following flavor

2016-06-20 21:24:35,345 | INFO  | tp2129545471-213 | actWadlGeneratorGrammarGenerator | 206 - com.sun.jersey.jersey-server - 1.17.0 | Couldn't find grammar element for class org.opendaylight.netconf.md.sal.rest.schema.SchemaExportContext
2016-06-20 21:24:36,866 | WARN  | r - ConfigPusher | FeatureConfigPusher              | 131 - config-persister-feature-adapter - 0.5.0.SNAPSHOT | Feature: startup, 0.0.0 is missing from features service. Skipping

and due to it hanging I see the timeouts as well

2016-06-20 21:29:44,213 | WARN  | ssionScavenger-3 | teInvalidatingHashSessionManager | 225 - org.ops4j.pax.web.pax-web-jetty - 3.2.6 | Timing out for 1 session(s) with id t0staxhnrwkt1g9w8l0dfovy3

During builds I get the following from the it tests I see blueprint errors

2016-06-20 21:21:54,673 | INFO  | Event Dispatcher | ServiceRecipe                    | 15 - org.apache.aries.blueprint.core - 1.4.4 | Unable to create a proxy object for the service .component-1 defined in bundle org.apache.karaf.deployer.features/3.0.6 with id. Returning the original object instead.
org.apache.aries.proxy.UnableToProxyException: java.lang.ClassFormatError: Duplicate interface name in class file Proxybfa29c46_5d38_4432_85ba_eb9ef2d6ea0c

and also during the features test.  In that case the blueprint errors below appear for topology-manager, sal-binding-broker-impl/1.4.0.SNAPSHOT  and forwardingrules-manager/0.3.0.SNAPSHOT

2016-06-20 21:14:39,858 | ERROR | ime-limited test | BlueprintContainerImpl           | 15 - org.apache.aries.blueprint.core - 1.4.4 | Unable to start blueprint container for bundle org.opendaylight.openflowplugin.applications.topology-manager/0.3.0.SNAPSHOT

Any ideas would be appreciated.
