>          Components: REST, Web (Undertow)
>    Affects Versions: 8.2.1.Final, 9.0.1.Final, 10.0.0.CR1

> When using Java EE 7, rest, jackson, with an AngularJS front end there's an intermittent exception when accessing REST endpoints. The exception stack trace in DEBUG level is here: http://pastebin.com/xjqMMkns . A reproducer can be found here https://github.com/ge0ffrey/optaconf .
> The exception seems to not affect the expected behavior of my application. I did see something similar for JBoss EAP 6.3.0 being categorized as blocker level due to the exception log level being inappropriate.
