removeAttachment on org.switchyard.bus.camel.CamelMessage leads to an java.lang.StackOverflowError

Issue

Following test:

public class CamelMessageTest {

    private static final String TESTDATASOURCE_NAME = "testdatasource";
    private static final String TEST_ATTACHMENT_ID = "testId";
    @Rule public ExpectedException expected = ExpectedException.none();

    @Test
    public void testRemoveAttachment() throws Exception {
        CamelMessage message = new CamelMessage(new DefaultExchange(new SwitchYardCamelContextImpl(false)));
        Assert.assertThat(message.getAttachment(TEST_ATTACHMENT_ID), IsNull.nullValue());

        message.addAttachment(TEST_ATTACHMENT_ID, new TestDataSource(TESTDATASOURCE_NAME));
        Assert.assertThat(message.getAttachment(TEST_ATTACHMENT_ID), IsNull.notNullValue());
        Assert.assertThat(message.getAttachment(TEST_ATTACHMENT_ID).getName(), Is.is(TESTDATASOURCE_NAME));

        message.removeAttachment(TEST_ATTACHMENT_ID);
        Assert.assertThat(message.getAttachment(TEST_ATTACHMENT_ID), IsNull.nullValue());
    }

}

Ends in StackOverflowException
