ConcurrentAccessException when resolving EL on Stateful bean
------------------------------------------------------------

                 Key: JBSEAM-4147
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-4147
             Project: Seam
          Issue Type: Bug
          Components: Test Harness
    Affects Versions: 2.1.1.GA
         Environment: jboss as 5.0
            Reporter: Sylvain Catudal


How to reproduce:
- Extend EntityQuery and make it a stateful EJB.
- Add a restriction that has EL in it that refers to that EJB
- Create a test that invokes the resultCount or resultList

While running the test, you'll get a ConcurrentAccessException.

Code example :

EJB :

@Name("authenticationList")
@Stateful
public class AuthenticationListBean extends EntityQuery<Authentication>
		implements AuthenticationList {

	private static final long serialVersionUID = 3302243104496804256L;

	private static final String EJBQL = "select authentication "
			+ "from Authentication authentication inner join fetch "
			+ "authentication.user";

	private static final String[] RESTRICTIONS = { 
		"authentication.user.userId = #{authenticationList.userId}" };

	private Long userId;

	public AuthenticationListBean() {
		setEjbql(EJBQL);
		setRestrictionExpressionStrings(Arrays.asList(RESTRICTIONS));
		setMaxResults(15);
	}

	public void setUserId(Long userId) {
		this.userId = userId;
	}

	public Long getUserId() {
		return userId;
	}

	@Remove @Destroy
	public void destroy() {
	}
}


Test :

public class FailingTest extends SeamTest {

	Long countBefore ;

	@Test
	public void test() throws Exception {

		new FacesRequest() {

			@Override
			protected void invokeApplication() {
				countBefore = (Long) getValue("#{authenticationList.resultCount}");
			}

		}.run();

	}
