Hi Soeren,
I believe you see the issue because you try to use Grizzly asynchronous
request processing within the synchronous Jersey resource.
Please take a look how to create async Jersey resource [1], you'd
probably need to use it to combine it with Grizzly async.
Please let me know if you have further questions.
WBR,
Alexey.
