OH2.2 - Asynchronous processing not supported on Servlet 2.x container

Setup, Configuration and Use Runtime
1

Upgraded to 2.2 on OpenHabian and now I’m getting a lot of exceptions in openhab.log, but only when I am running PaperUI, that I can tell. Exceptions happen every few seconds while on PaperUI. Everything else seems to be working okay. I know this isn’t very much as far as details, but I’m hoping it will trigger an ‘oh yeah, do this’ moment with someone.

Thanks, this worked great. Maybe a bug report to the debian package?

FYI… Just ran an upgrade on my Beagle Bone Black deployment (2.5.2 --> 2.5.3) and I ended up have to do this as well. First it its happened to me. Upgrades 2.5.0 --> 2.5.1 --> 2.5.2 all did not experience this issue.
