      Description

      Running on IBM z13 mainframe, after installing IBM JDK 8, I am unable to pull the branch source from GitHub.    This is really a critical/major problem, since the only other JDK for the z13 would be OpenJDK, which uses Zero VM (interpreted mode only), so performance is terrible, so bad in fact that the machine runs at 200-300%, and cannot keeps up with long running jobs on the agents. 

      // code placeholderjava.net.UnknownServiceException: Unable to find acceptable protocols. isFallback=false, modes=[ConnectionSpec(cipherSuites=[TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_3DES_EDE_CBC_SHA], tlsVersions=[TLS_1_2, TLS_1_1, TLS_1_0], supportsTlsExtensions=true), ConnectionSpec(cipherSuites=[TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256, TLS_DHE_RSA_WITH_AES_128_GCM_SHA256, TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA, TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA, TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA, TLS_DHE_RSA_WITH_AES_128_CBC_SHA, TLS_DHE_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_AES_128_GCM_SHA256, TLS_RSA_WITH_AES_128_CBC_SHA, TLS_RSA_WITH_AES_256_CBC_SHA, TLS_RSA_WITH_3DES_EDE_CBC_SHA], tlsVersions=[TLS_1_0], supportsTlsExtensions=true), ConnectionSpec()], supported protocols=[TLSv1]

      It looks like this issue: https://github.com/watson-developer-cloud/java-sdk/issues/603  Where the a fix may have gone into okhttp..  The issue seems quite old, but it seems the problem lies in that area.
