Using @PostConstruct annotation in Spring 3.0.0.RC1

I am using @PostConstruct annotation (to mark init method in a bean) in Spring version 3.0.0.RC1. I start this web application in Jetty and get the following exception:

failed ContextHandlerCollection@1a88001

Does anybody knows if it is a bug in RC1 or if there is a work around?

I know this is an old question, but I'll still post the answer that I found for the sake of posterity.

This is a dependency issue. In my project's dependency tree, I noticed that the cxf-rt-transports-http-jetty dependency had a transitive dependency on spring-web.2.5.5. The OrderComparator.sort method wasn't implemented until later, so unless you add a direct dependency definition for a newer version of spring-web to your POM, spring will fall back to the older version that jetty needs.

To fix this, I added dependency definitions for the latest spring-core and spring-web artifacts to my POM.
