Hello,
I'm trying to create a HttpSession, I injected the HttpServletRequest using the @context annotation in my endpoint controller but a NullPointerException is thrown.

The debugger tells me that a proxy is "correctly" injected in the servletRequest parameter and I am able to get some information from it (such as the request URI).

I am running my bundle on Eclipse Kura 3.2 with Equinox.

REST controller :

@Path("/auth")
public class SecurityController {
	private static Logger logger = LoggerFactory.getLogger(SecurityController.class);
	private EUserDAO userDAO;

	@POST
	@RolesAllowed(PUBLIC_ROLE)
	@Consumes(MediaType.APPLICATION_JSON)
	@Produces(MediaType.APPLICATION_JSON)
	public Response auth(AuthenticationPayload payload, @Context HttpServletRequest servletRequest) {
		if (payload == null || payload.getUsername() == null || payload.getPassword() == null) {
			return Response.status(Response.Status.BAD_REQUEST).build();
		}

		final EUser user;

		try {
			user = userDAO.findByName(payload.getUsername());
		} catch (SQLException e) {
			logger.error("Error getting users list", e);
			return Response.status(Response.Status.INTERNAL_SERVER_ERROR).build();
		}

		if (user == null) {
			// Unknown user
			return Response.status(Response.Status.UNAUTHORIZED).build();
		}

		if (user.getPinCode() == null || !user.getPinCode().equals(payload.getPassword())) {
			// Wrong password
			return Response.status(Response.Status.UNAUTHORIZED).build();
		}

		HttpSession oldSession = servletRequest.getSession(false);
		if (oldSession != null) {
			oldSession.invalidate();
		}

		HttpSession session = servletRequest.getSession();
		session.setMaxInactiveInterval(30 * 60);

		return Response.ok().build();
	}
}

Does anybody have an idea that could help me ? I still don't know if the problem comes from osgi-jax-rs-connector, Jersey or Equinox...
