I have set  zookeeper.ssl.ciphersuites :TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_ECDSA_WITH_AES_256_GCM_SHA384,TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 in ZKClientConfig ,but when i dump the tcp package , i find the ciphersuites do not match what i set

i debug with the code of zookeeper

maybe it need be add 

sslEngine.setEnabledCipherSuites(cipherSuites);   after read tag 1

cipherSuites can get from  clientConfig
