Number of annotations at JUnit test incorrect

I have created some custom annotations to use for system tests which are run via JUnit.

A test e.g. looks like this:

@TestCaseName("Change History")
public class ChangeHistory extends SystemTestBase
{    
    @Test
    @Risk(1)
    public void test()
    {
...

I am now implementing a Test Runner which shall report the test name, the risk and the somewhere for documentation purposes.

public class MyRunner extends BlockJUnit4ClassRunner
{
    ...
    @Override
    protected void runChild(final FrameworkMethod method, RunNotifier notifier) 
    {
        ...
        System.out.println("Class annotations:");
        Annotation[] classanno = klass.getAnnotations();
        for (Annotation annotation : classanno) {
            System.out.println(annotation.annotationType());
        }

        System.out.println("Method annotations:");
        Annotation[] methanno = method.getAnnotations();
        for (Annotation annotation : methanno) {
            System.out.println(annotation.annotationType());
        }

The output is 

Class annotations:
Method annotations:
interface org.junit.Test

So getAnnotations() seems to return annotations of JUnit only and not all annotations. This is not mentioned in the documentation of JUnit:

Returns the annotations on this method

The return type is java.lang.Annotation which made me believe that I can use any annotation. I defined the annotation like follows - I just used it and when there was an error I let Eclipse generate the annotation:

public @interface Risk {
    int value();
}

How do I get all annotations of the test class and test method?

You need to set the retention policy of the Risk annotation to RUNTIME. Otherwise, the annotation will be discarded after the compilation and won't be available during the execution of the code.

This should be working:

import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

@Retention(RetentionPolicy.RUNTIME)
public @interface Risk {
  int value();
}
