AuthenticationCredentialsNotFoundException

[siarhei-poludvaranin]

Hello,
When I mark my view class with @secured annotation sometimes I get this exceptoion:

...
org.springframework.security.authentication.AuthenticationCredentialsNotFoundException: An Authentication object was not found in the SecurityContext
at org.springframework.security.access.intercept.AbstractSecurityInterceptor.credentialsNotFound(AbstractSecurityInterceptor.java:339)
at org.springframework.security.access.intercept.AbstractSecurityInterceptor.beforeInvocation(AbstractSecurityInterceptor.java:198)
...

When I test the code locally - everything works fine. But on the staging server I got such exception.
Has anyone faced it? How can I solve the problem?
My security config is the same as shown in the security-sample.

I have not been able to reproduce this so I'm closing the ticket. If you're still experiencing the problem with the latest version, we can reopen the ticket.

I have that problem for quite a while now "Sometimes getting AuthenticationCredentialsNotFoundException between multiple requests" but on my local machine as well.

From my stackoverflow question:

"I am having the problem of sometimes getting a AuthenticationCredentialsNotFoundException. At the moment I am absolutely not sure what's causing this.

It is "very likely" that I'm getting this exception if I login right after the server started. After logging in I am not getting this exception - for a while. Now assume there is a request loadData(). If I repeatedly send this request to the server it appears to work for a while but then, all of a sudden, I am getting this exception again. Sometimes just once, sometimes multiple times but not "forever". Just a few exceptions and then it's working again."

Also with the latest version of Vaadin4Spring?
