Asynchronous operations

[Creepix]

I'm using play2war 1.4-beta1 plugin with play 2.4.6 on tomcat 8. There is SPNEGO filter on that tomcat, which I want to use with my play application in purpose to have remote user name. As I understand http asynchronous request processing is available, but I'm getting:

java.lang.IllegalStateException: A filter or servlet of the current chain does not support asynchronous operations.
org.apache.catalina.connector.Request.startAsync(Request.java:1621)

Any suggestions how to fix it?

How did you configure the filter ?
