avalon:bridge causes exception in eclipse

[Leszek Gawron]

Hello,

When I have a Spring Nature added to a cocoon project I get the 
following exception in eclipse:

Description     Resource        Path    Location        Type
Error occured processing XML 'null'. See Error Log for more details     
applicationContext.xml  /my-webapp/src/main/webapp/WEB-INF      line 24 Spring 
Beans Problem

in workspace logs:

Is this a problem of STS tools or cocoon itself ?
