problem with running Spring JUnit test case under Intellij

I am having problem to run Spring JUnit test case under Intellij. with error

Configuration problem: Duplicate <http> element detected

The error happens when I load all the Spring's application context which include Spring Security configuration. E.g.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath*:**/*Context.xml"})
@Transactional
public class MyTestCaseWithAllContexts {
     ...
}

but if I only load specific context only it works. E.g.

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"classpath*:coreContext.xml","classpath*:myOtherContext.xml"})
@Transactional
public class MyTestCaseWithSomeContexts {
     ...
}

I am not sure whether it is problem with Intellij or maybe my project setup. My project is set up to use

project
  |- core-module
  |         |- src
  |             |- main
  |                  |- java
  |                       |- MyTestCaseWithAllContexts
  |                       |- MyTestCaseWithSomeContexts
  |                       |- ...
  |- web-module
            |- src
                |- main
                     |- resources
                            |- coreContext.xml
                            |- myOtherContext.xml
                            |- securityContext.xml (location of Spring Security etc)
                            |- ...

I use

• Spring 3
• Maven 2.2.1

Any insight or help is appreciated. Thanks
