Support TestNG and JUnit 4 expected exceptions

Support detection of:

@org.junit.Test(expected=MyException.class)
@org.testng.annotations.Test(expectedExceptions=

{MyException.class,MyOtherException.class})
@org.testng.annotations.Test @org.testng.annotation.ExpectedExceptions({MyException.class,MyOtherException.class}

)

Ensure instrumented test methods that capture test results do not flag these exceptions as test faiiures/errors. Also ensure these test methods flag the absence of the exceptions as test failures.
