Hi Joseph,
I was seeing this as well, but further debugging revealed that this
was caused by a call to this method before the JerseyEndpoint
component was activated. While having a NPE at this state it not nice
it should not have any side effects.
As this Exception is not related to any HTTP request but thrown in the
context of the OSGI initialization thread I do not think that it is
directly related to your problem. However your problem might be
related to STANBOL-1073.
Anyways I will make some small changes so that will prevent this NPE
from occurring.
best
Rupert
