A test throwing an unserializable InvocationTargetException passes as green

[jgrgt]

TestVerticle.startTests() catches InvocationTargetExceptions, but in one of my Groovy-based tests, it caught a groovy.lang.MissingMethodException, and tries to handle it. This causes a serialization error in VertxAssert on line 51. This exception is uncaught, and causes no failure to be logged to Vertx, making the test pass as successful.

I tried 'fixing' this by again surrounding the VertxAssert.handleThrowable(targetEx); with a try/catch, but that messes up the output stream for some reason. I haven't found time to look deeper into it, so I don't have a patch to offer. I'm afraid. My workaround so far is to override startTests():

    @Override
    protected void startTests() {
        String methodName = container.config().getString("methodName");
        try {
            Method m = getClass().getDeclaredMethod(methodName);
            m.invoke(this);
        } catch (InvocationTargetException e) {
            // Conflict with Groovy causes sometimes silent InvocationTargetExceptions, so we always fail here.
            VertxAssert.fail(e.getMessage());
        } catch (Throwable t) {
            // Problem with invoking
            VertxAssert.handleThrowable(t);
        }
    }

The exception causing the problems:

groovy.lang.MissingMethodException: No signature of method: ...
