Hi,
explicitly thrown Exceptions like
throw new Exception();
should be marked as covered. We have an integration test for this
<https://github.com/jacoco/jacoco/blob/master/org.jacoco.core.test.validation.java5/src/org/jacoco/core/test/validation/java5/targets/ExceptionsTarget.java#L77>.
Only lines with implicitly thown exception like
methodThatThrowsAnException();
are not marked as covered due to a technical limitation. This is documented in
the FAQ <https://www.jacoco.org/jacoco/trunk/doc/faq.html>:
> Source code lines with exceptions show no coverage. Why?
