Hi, community I found that many cases failed on travis, randomly.
https://github.com/apache/incubator-dubbo/issues/2492 https://github.com/apache/incubator-dubbo/issues/2490 https://github.com/apache/incubator-dubbo/issues/2484 https://github.com/apache/incubator-dubbo/issues/2482 https://github.com/apache/incubator-dubbo/issues/2462 But when rebuild them, it's ok. So I suggest that issue all of the failed cases, so that the community can check it out later.
