Spring security3 isEraseCredentialsAfterAuthentication() -No method found exception

[vkjk89]

Hi Rob,
Thanks for your help.
I removed aopalliance bean from my root applicationContext and things worked.
Can you please tell me whats the relationship between aopalliance bean and my spring security context ? Is there any conflict ?

I suggest you read about AOP in the Spring Reference. You might also look at the Getting Started with Spring Security 3.1 presentation from SpringOne 2011 at around 1 hour in. In short, when you proxy an object using interface based proxying, it exposes only the interface methods. You could switch to CGLIB based proxies, which will still have all the methods available on it. Keep in mind there are certain limitations with CGLIB proxies (i.e. cannot proxy final classes, non-default constructors, etc). Your other option is to just not join on the Spring Security project.
