Description of problem: The following three test classes display this issue. (RemoteCacheManagerTest, ClientAsymmetricClusterTest, and ServerRestartTest) This is what I see when trying to run RemoteCacheManagerTest: a) A Hot Rod server is started on port 15233 b) The default constructor for the RemoteCacheManager is called, and a server on the default port (11222) is added to the configuration object c) TcpTransportFactory::pingServers() fails and throws a HotRodClientException "Failed to connect Operation now in progress" Side note: Can that error message be changed to something more understandable, like "Ping operation to <server>:<port> failed"? At first this seems like a test configuration issue, and I have been trying to figure out where the 15233 port is set. Then I tried running the same test using the Java Hot Rod client in the Infinispan project, and it also starts a server on port 15233. In this case the test succeeds, though. Now I am wondering if the implementation of the ping operation is different between the two clients.
This issue is related to host name resolution under IPv6. Setting the "HOTROD_IPSTACK=IPV4" environment variable is a workaround until this is fixed. This error can still occur even if this environment variable is set.
Alan does this still fail ?
