These exceptions are harmless in nature.

OpenDaylight uses Jersey framework to support JAX-RS compliant Northbound API.
OSGi makes sure the dependent modules are loaded first and before moving a module
into RESOLVED state. But the module implementation can result in one bundle become
ACTIVE before the other. This can be resolved properly by having these sequentialized
by monitoring the service bringup order.
In this case, com.sun.jersey.spi.container expects the jersey-server and core to be active too soon causing the exceptions as seen in this bug.
But, as per OSGi specification, any bundle can be independently shutdown and restored and the dependent bundles must be robust in handling this. Fortunately, the jersey and dependent framework bundles handles this scenario properly and hence this exception is just informational and has no impact on the running system.

Having said that, experimenting with startlevel infact solves this problem and
the exception is not seen any more.
