--------------------------------

             Summary: A performance bug
                 Key: ARIES-1702
                 URL: https://issues.apache.org/jira/browse/ARIES-1702
             Project: Aries
          Issue Type: Bug
          Components: Blueprint
    Affects Versions: blueprint-core-1.7.0
            Reporter: Hao Zhong


I notice that DirObjectFactoryHelper.getObjectInstanceUsingObjectFactoryBuilders has the following code:
 for (ServiceReference ref : refs) {
                ObjectFactoryBuilder builder = (ObjectFactoryBuilder) Utils.getServicePrivileged(callerContext, ref);
                try {
                    factory = builder.createObjectFactory(obj, environment);
                } catch (NamingException e) {
                    // TODO: log it
                } finally {
                    callerContext.ungetService(ref);
                }
                if (factory != null) {
                    break;
                }
            }
The above code is copied from a buggy version of ObjectFactoryHelper.getObjectInstanceUsingObjectFactoryBuilders. Please refer to ARIES-1068 for details.
The buggy version of ARIES-1068 is identical. Its fixed version is as follow:
 ServiceReference[] refs = objFactoryStC.getServiceRefs();
            
        if (refs != null) {
            Arrays.sort(refs, Utils.SERVICE_REFERENCE_COMPARATOR);
            
            for (ServiceReference ref : refs) {
              if (canCallObjectFactory(obj, ref)) {
                ObjectFactory factory = (ObjectFactory) objFactoryStC.getService(ref);

                try {
                    result = factory.getObjectInstance(obj, name, nameCtx, environment);
                } catch (NamingException ne) {
                  // Ignore this since we are doing last ditch finding, another OF might work.
                }

                // if the result comes back and is not null and not the reference
                // object then we should return the result, so break out of the
                // loop we are in.
                if (result != null && result != obj) {
                    break;
                }
              }
            }
        }
