InitilizationError when JunitTest with Maven

I'm trying to do some Junit-Test's with Maven3 but always get some initilizationError(some testclass here) when executing test which have JUnit-Annotations (all other tests run fine). When I run the tests in Eclipse all is fine. But running the tests with maven will break. My Testproject is packaged as eclipse-plugin. I use the maven-osgi-test-plugin.

My testclass is annotated by:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations="classpath:applicationContext.xml")
@TransactionConfiguration
public class ArtifactManagerTest extends
    AbstractTransactionalJUnit4SpringContextTests {...

For every testclass annotated with @ContextConfiguration there is the classname-test.xml file. In this configuration-file I import the applicationContext-Test.xml by "classpath:"

My pom.xml of the test-plugin looks like:

<groupId>foo.bar</groupId>
<artifactId>company.xyz</artifactId>
<version>1.0.0-SNAPSHOT</version>
<packaging>eclipse-test-plugin</packaging>

<build>
 <plugins>
  <plugin>
   <groupId>org.sonatype.tycho</groupId>
   <artifactId>maven-osgi-test-plugin</artifactId>
   <configuration>
    <useUIHarness>true</useUIHarness>
    <testSuite>company.xyz.test</testSuite>
    <testClass>company.xyz.AllTests</testClass>
    <argLine>-Xmx512m</argLine>
    <bundleStartLevel>
     <bundle>
      <id>org.eclipse.equinox.ds</id>
      <level>1</level>
      <autoStart>true</autoStart>
     </bundle>
    </bundleStartLevel>
   </configuration>
   <inherited>true</inherited>
  </plugin>
 </plugins>
</build>

The failure output is as follows:

In the surefire-reports I see the java.class.path is set to my local maven repository to 'org.eclipse.equinox.launcher-1.1.0.v20100507.jar'

It looks like the classpath isn't set correct, so maven can't find the applicationContext.xml? But how to do this correct?

Please make sure that methods of @BeforeClass and @AfterClass are "public static void" and no arguments in your test case class ArtifactManagerTest.

Edit: the InitializationError is thrown when validate @BeforeClass and @AfterClass fails, so @BeforeClass isn't even executed.

If possible, use following code to get failure info:

Result r=new JUnitCore().run(ArtifactManagerTest.class); 
for(Failure f:r.getFailures()){ 
    System.out.println(f); 
}
