I can reproduce it but still see the correct response returned to the client. 
Do you also see correct responses? I'll dig into it as soon as I can. Thanks 
for reporting.

This is now fixed in master. Does it work for you?

Yes i do, still, it's annoying ;)

Hmm, if you still see the exception, I need a running sample application that 
reproduces the problem. Can you share one?

Any objections that I close this ticket?

Sorry, i don't have a simple sample, is it fixed?

How should I help you if I cannot reproduce your problem (after having already 
pushed a fix to master) and you don't share a failing app that demonstrates 
your problem?

Have you actually checked out the latest sources and built the plugin? I also 
added an integration test there, to demonstrate that it is working 
(https://github.com/krasserm/grails-jaxrs/blob/master/test/integration/org/grail
s/jaxrs/itest/JaxrsControllerIntegrationTests.groovy#L73).

I'll close the ticket now. Should you want me to help you, please re-open this 
ticket and attach a failing sample app or a failing test.

Cheers!
