Cory Prowse commented on JCR-2701:
----------------------------------

As requested by Alexander Klimetschek, here is a code sample for attempting to create the
new workspace using a fresh session:

---
package au.jcr;

import javax.annotation.PostConstruct;
import javax.annotation.Resource;
import javax.ejb.Singleton;
import javax.ejb.Startup;
import javax.jcr.AccessDeniedException;
import javax.jcr.InvalidItemStateException;
import javax.jcr.ItemExistsException;
import javax.jcr.LoginException;
import javax.jcr.NoSuchWorkspaceException;
import javax.jcr.PathNotFoundException;
import javax.jcr.ReferentialIntegrityException;
import javax.jcr.Repository;
import javax.jcr.RepositoryException;
import javax.jcr.Session;
import javax.jcr.SimpleCredentials;
import javax.jcr.UnsupportedRepositoryOperationException;
import javax.jcr.lock.LockException;
import javax.jcr.nodetype.ConstraintViolationException;
import javax.jcr.nodetype.NoSuchNodeTypeException;
import javax.jcr.version.VersionException;

@Startup
@Singleton
public class JcrStartupSingleton {

    @Resource(name = "jcr/repository", type = javax.jcr.Repository.class)
    private Repository repository;

    @PostConstruct
    public void setupWorkspaces() throws RepositoryException {
        addExampleNodeToProductionWorkspace();

        createStagingWorkspaceFromProductionWorkspace();
    }

    private void addExampleNodeToProductionWorkspace() throws LoginException, NoSuchWorkspaceException,
RepositoryException,
            ItemExistsException, PathNotFoundException, VersionException, ConstraintViolationException,
LockException,
            AccessDeniedException, ReferentialIntegrityException, InvalidItemStateException,
NoSuchNodeTypeException {
        final Session session = repository.login(new SimpleCredentials("admin1", "".toCharArray()),
"production");
        try {
            session.getRootNode().addNode("example");
            session.save();
        } finally {
            session.logout();
        }
    }

    private void createStagingWorkspaceFromProductionWorkspace() throws LoginException, NoSuchWorkspaceException,
            RepositoryException, AccessDeniedException, UnsupportedRepositoryOperationException
{
        final Session freshSession = repository.login(new SimpleCredentials("admin1", "".toCharArray()),
"production");
        try {
            // Exception is thrown here (is line 55)
            freshSession.getWorkspace().createWorkspace("staging", "production");
        } finally {
            freshSession.logout();
        }
    }
}

(Exact same exception as before but on line 55 of JcrStartupSingleton)
