Subject Re: Tomee 7.0.1 JAX-RS AsyncReponse throws NullPointerException
Date Sun, 07 Aug 2016 12:08:46 GMT
Hmm,

This code is in cxf right? Pretty sure it works == not where the issue is.
Is keycloak asyncSupported? If not will likely fail.

Best for such an issue is to share on github a sample project failling -
either with a tomee unit test or tomee-maven-plugin. Is that an option?
