-------------------------------------
Resolution: Not A Problem

> ----------------------------------------------------------------------------
>
> Key: FELIX-4751
> URL: https://issues.apache.org/jira/browse/FELIX-4751
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: framework-4.0.1
> Environment: Centos 6.0 JDK 6
> Reporter: Chenqiulin
>
> I register service like this:
> {code}
> public void start(BundleContext context) throws Exception {
> Dictionary props = new Hashtable();
> // service.pid
> String symbolicName = (String) context.getBundle().getHeaders()
> .get("Bundle-SymbolicName");
> props.put("service.pid", symbolicName);
> props.put(Constant.COMMANDNAME, "manager");
>
> serviceRegistrationRuntime = context.registerService(
> AgentAction.class.getName(), new
> ManagerAction(context), props);
> logger.info("manager Service regist success.");
> }
> {code}
> and I get the service like this:
> {code}
> public Response handle(Message message) {
> ServiceReference[] serviceRefs = null;
> Response result = null;
> try {
> String mess = message.getContent().toString();
> logger.debug(mess);
> Map map = JsonUtil.toBean(mess, Map.class);
> logger.info("begin to handle message " +
> map.get(MODULENAME));
> serviceRefs = context.getAllServiceReferences(
> AgentAction.class.getName(), "(" +
> Constant.COMMANDNAME
> + "=" +
> map.get(MODULENAME) + ")");
> // serviceRefs = context.getAllServiceReferences(
> // AgentAction.class.getName(),null);
> if (serviceRefs.length == 0) {
> throw new Exception("has not command service
> like this");
> }
> if (serviceRefs.length > 1) {
> throw new Exception("more than one command
> service like this");
> }
> AgentAction action = (AgentAction) context
> .getService(serviceRefs[0]);
> // handle the command
> result = action.handle(message);
> } catch (Exception e) {
> result = message.createResponse();
> result.setErrorMsg( e.getMessage());
> logger.error(e.getMessage(), e);
> }
> return result;
> }
> {code}
> the phenomenon is I always catch the Exception(about 50%) like this:
> {code}
> ERROR - cn.tianya.amm.agent.service.AgentMessageHandler - Invalid
> BundleContext.
> java.lang.IllegalStateException: Invalid BundleContext.
