Flex Unit Test on Maia-10558

When I run a Flex Unit Test on Maia 10558, I get the following error:

Error:(55, 0) Access of undefined property className in package test.

This is the class, that has been built by Maia:

<local:LearnApplication____FlexUnitLauncherBase xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:local="*"
                            implements="flexunit.framework.TestListener">

        import flexunit.framework.Test;

        import test.DummyUnitTest;


        private const PORT : Number = 07832;
        private const MODULE : String = "LearnApplication";

        protected override function getPort():Number {
            return PORT;

            __testSuite__.addTestSuite(test.DummyUnitTest);


            onRunStarted(__testSuite__.countTestCases());

            var testResult : TestResult = new TestResult();
            testResult.addListener(this);

        }

        public function addError(test:Test, error:Error):void {
            onTestFailed(getTestInfo(test), error.message, error.getStackTrace());
        }

        public function addFailure(test:Test, error:AssertionFailedError):void {
            addError(test, error);
        }

        public function endTest(test:Test):void {
            onTestFinished(getTestInfo(test));
        }

        private static function getTestInfo(test: Test) : String {
            return test.className + "." + (test as TestCase).methodName;
        }

This is on Mac OS-X 10.5.7, latest Java 1.6.0_13-b03-211.
