AEM 6.5 asynchronous servlet

Hi Experts,

With AEM 6.5 supporting servlet api version 3.1, is there a way to write asynchronous servlets?

I could not find any documentation on sling/aem knowledge base.

Also, on while trying it seems that AsyncContext acontext = req.startAsync(); alwasy fails.

I reckon all the servlets and filter in the chain of a servlet requests has to have async enabled.

Anyone managed to get asynchronous servlets working in AEM 6.5?

Thanks,

A
