IdMapService: No Descriptor value available

[Jdruwe]

Hello

I am getting the following info logs each second in my error.log:

[IdMapService-initializer] org.apache.sling.discovery.commons.providers.spi.base.IdMapService init:
init failed: java.lang.Exception: No Descriptor value available

I only get the error after installing https://github.com/hstaudacher/osgi-jax-rs-connector​ the JAX-RS OSGI connector:

<embedded>
      <groupId>com.eclipsesource.jaxrs</groupId>
      <artifactId>publisher</artifactId>
      <target>${target.install}/${startlevel.2}</target>
</embedded>

NOTE: this always worked without the logging in earlier versions of AEM (without SP2 and CFP10)

I am not really sure why I am getting this error or how I can resolve it but I pinpointed the place of error:

The IdMapService class has the following code which calls the init() method each second:

@Activate
protected void activate(BundleContext bundleContext) {
    this.bundleContext = bundleContext;
    registerEventHandler();
    startBackgroundCheck("IdMapService-initializer", new BackgroundCheck() {
        @Override
        public boolean check() {
            try {
                return init();
            } catch (Exception e) {
                logger.error("initializer: could not init due to "+e, e);
                return false;
            }
        }
    }, null, -1, 1000 /* = 1sec interval */);
}

In the init() method you can find the following line:

DiscoveryLiteDescriptor descriptor = DiscoveryLiteDescriptor.getDescriptorFrom(resourceResolver);

The DiscoveryLiteDescriptor will try to fetch the 'OAK_DISCOVERYLITE_CLUSTERVIEW' descriptor from the session repository:

public static final String OAK_DISCOVERYLITE_CLUSTERVIEW = "oak.discoverylite.clusterview"
...
String descriptorStr = session.getRepository().getDescriptor(DiscoveryLiteDescriptor.OAK_DISCOVERYLITE_CLUSTERVIEW);
if (descriptorStr == null) {
   throw new Exception("No Descriptor value available");
}
...

As you can see the session repository only contains 6 descriptors and 'oak.discoverylite.clusterview' isn't one of them, resulting in the exception.

Am I the only one experiencing this issue. Any help is greatly appreciated!
