If protocol is AJP, AbstractAjpProcessor.action will throw
UnsupportedOperationException.
In org.apache.catalina.connector.InputBuffer#avaliable(), readForAvailable is
not enough to avoid IS_COMET action.
I think we should also check the protocol, since IS_COMET only support HTTP.
The only way to I can figure out is to use
Thread.currentThread.getName().isStartsWith("http"), but maybe there is
something better.

Subject:svn commit: r1712529 - in /tomcat/tc8.0.x/trunk/java/org/apache:
catalina/connector/ catalina/core/ coyote/ coyote/ajp/ coyote/http11/
Author: markt
Date: Wed Nov 4 10:55:12 2015
New Revision: 1712529
URL: http://svn.apache.org/viewvc?rev=1712529&view=rev
Log:
Follow-up to r1712081.
Comet is not-blocking too, so it also needs to trigger a read on a call to
available() if no bytes are in the buffer
