ReflectionTestUtils: Testing exceptions in constructors

[alpkaanaksu]

Is your feature request related to a problem? Please describe.
I wanted to test that a constructor throws an IllegalArgumentException, there is no method in ReflectionTestUtils to do that.

Describe the solution you'd like
A new method (e.g. newInstanceRethrowing), which rethrows the underlying exception (cause), if a problem occurs during instantiation. We would be able to use assertThrows with that method.

Describe alternatives you've considered
I created a method myself:

public static <T extends Throwable> void assertConstructorThrowsException(String message, Class<T> exception, Constructor<?> constructor, Object... arguments) {
        assertThrows(exception, () -> {
            try {
                constructor.newInstance(arguments);
            } catch (InvocationTargetException | InstantiationException | IllegalAccessException e) {
                throw e.getCause();
            }
        }, message);
    }
