If you are using the @ExpectedAnnotation from spring, clover will report 0% code coverage and indicate the tests failed. e.g. the following test case will report no code coverage:

@Test
@ExpectedException(Exception.class)
public void testApp() throws Exception
{
     App a = new App();
     a.doStuff(); //a.doStuff throws an exception
}

Using the JUnit 4.x annotations works and the report will show the test passed and the code coverage will be reported correctly:

@Test(expected = Exception.class)
public void testApp() throws Exception
{
     App a = new App();
     a.doStuff(); //a.doStuff throws an exception
}

Would be nice if clover could understand the spring annotations too.
