ArquillianProxyException instead of ConstrainViolationException in JUnit @Test(expected)

When using Arquillian to test my (JPA) entities as part of an integration test, everything seems seems to work, except testing for ConstraintViolations. For example it should not be possible to persist an entity instance which had null values in fields annotated with Bean Validation's @NotNull. Instead of a ConstrainViolationException I get ArquillianProxyException: 

Unexpected exception, expected<javax.validation.ConstraintViolationException> but was<org.jboss.arquillian.test.spi.ArquillianProxyException>

This is my simple test: 

 @Test(expected = ConstraintViolationException.class) // not set required fields
public void shouldNotCreateNewFirm() {

    // Create instance of firm entity
    Firm firm = new Firm("[email protected]", "allegro", "aAle2@", "Allegro Ltd.");

    // persist the firm to the database
    transaction.begin();
    em.persist(firm);

    em.remove(firm);

    transaction.commit();
}

and error details: 

    Caused by: org.jboss.arquillian.test.spi.ArquillianProxyException: javax.validation.ConstraintViolationException : Validation failed for classes [pl.salonea.entities.Firm] during persist time for groups [javax.validation.groups.Default, ]

Is your Firm instance serializable? The ConstraintViolation contains a reference to the root bean (your Firm instance). To be able to serialize the ConstraintViolationException the full exception must be serializable. My guess is that this is not the case in your use case. In this case Arquillian needs to send back a proxy. The docs for ArquillianProxyException states:

Exception class used when a proxied exception cannot be created. This exception type is is thrown instead and contains information about the proxied class and a hint about why it could not be thrown.

Actually on second thought, there is also ClassNotFoundException which might indicate that there are missing classes on the client side. It might help to see the full stack trace.

I have been working on a similar example using Bean Validation in the context of an integration test. I encountered the same problem as you described in your question. I am still not sure why it causes an ArquillianProxyException as all used classes implement Serializable but I found a possible solution proposed by David Belzer which can be found here: https://blog.david-belzer.de/2014/04/arquillian-unittest-exceptionhandling/ (german blog post)

Instead of stating the expectation in the @Test annotation a @Rule annotated ExpectedException field should be declared for this use case.

The usage could look like this (adapted from the blog post):

    @Rule
    public ExpectedException thrown = ExpectedException.none();

    @Test
    public void shouldNotCreateNewFirm() {

        // not set required fields
        thrown.expect(ConstraintViolationException.class);

        // Create instance of firm entity
        Firm firm = new Firm("[email protected]", "allegro", "aAle2@", "Allegro Ltd.");

        // persist the firm to the database
        transaction.begin();
        em.persist(firm);

        em.remove(firm);

        transaction.commit();
    }
