Not installing optional component warning - StandardServletAsyncWebRequest

[chrisburrell]

Hi All

Just trying to work out if the following stacktrace is an issue in JBoss or an issue with Spring?

10:57:16,220 WARN  [org.jboss.as.ee] (MSC service thread 1-16) JBAS011006: Not installing optional component org.springframework.web.context.request.async.StandardServletAsyncWebRequest due to exception: org.jboss.as.server.deployment.DeploymentUnitProcessingException: JBAS011054: Could not find default constructor for class org.springframework.web.context.request.async.StandardServletAsyncWebRequest

Also, I'm a bit confused at the message. Why is JBoss expecting to find a default constructor in this class?

Cheers

This doesn't help. I understand that there is nothing to worry about - but I'd like to know why it's even a warning in the first place, and how to resolve that. At the moment I've resorted to a log filter.

I had the very same message JBAS011006: Not installing optional component but for a component of my own.  I eventually discovered that it was trying to look up a session bean using "module/BeanName/local" in its constructor.  Once I changed that to "java:app/module.jar/BeanName!Bean.Interface.Class.In.Excruciating.Detail" then the message went away.

I appreciate that StandardServletAsyncWebRequest isn't a component of yours, but you might want to have a look at its source - you might be able to contribute an improvement back to the spring framework.
