Tests for maven plugins are incompatible with maven 3.0.4

I have a simple test for maven plugin:

public class SimpleMavenTest extends AbstractMojoTestCase {

    @Override
    protected void setUp() throws Exception {
        super.setUp();
        // code
    }

    public void testCase() throws Exception {
        // test case
    }

    @Override
    protected void tearDown() throws Exception {
        // code
        super.tearDown();
    }
}

with such maven-surefire-plugin configuration:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <configuration>
        <forkMode>never</forkMode>
      </configuration>
    </plugin>
  </plugins>
</build>

Until maven 3.0.4 has been released, my SimpleMavenTest run succesfully. But when I run the test using maven 3.0.4, the next error was occurred:

java.lang.IllegalStateException: The internal default plexus-bootstrap.xml is missing. This is highly irregular, your plexus JAR is most likely corrupt.

I looked here: http://maven.apache.org/plugins/maven-surefire-plugin/examples/class-loading.html and tried to change maven-surefire-plugin configuration in a such way:

<configuration>
        <forkMode>once</forkMode>
</configuration>

Everything works fine. But if I make:

<forkMode>never</forkMode>

the above error is occured. It's strange, because on maven 3.0.3 and previous maven versions the test was run without any errors. Any ideas?

I opened a bug on jira.codehaus.org and got the answer that this trouble was resolved in maven-surefire-plugin v.2.11. As I used 2.10 version, the error was occurred. The latest surefire plugin version is 2.12, so change surefire configuration as follows:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.12</version>
    <configuration>
        <forkMode>never</forkMode>
    </configuration>
</plugin>

and tests will run successfully.
