AsyncContext#start runs in caller thread ---------------------------------------- Key: WFLY-3295 URL: https://issues.jboss.org/browse/WFLY-3295 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Web (Undertow) Affects Versions: 8.1.0.CR1 Reporter: Philippe Marschall Assignee: Stuart Douglas Fix For: 8.1.0.Final Attachments: AsyncServlet.java {{javax.servlet.AsyncContext.start(Runnable)}} seems to run the runnable in the caller thread. In order for this method to be useful it should be run in a different thread. I'll attach a class to demonstrate the issue.
