You can do this actually as `assertThrows` returns the exception thrown:

            assertEquals("message", assertThrows(
                IllegalArgumentException.class, 
                () -> RadialGradient.valueOf("radial-gradient(radius -100, red 0%, blue 30%, black 100%)")
            ).getMessage());
