the es cluster version is 2.3.3, both client and client version has java version of 1.7\_update80  
when i using elasticsearch 2.3.3 jar to start a Transport client . code like this:

client =TransportClient.builder().addPlugin(ShieldPlugin.class).settings(settings()).build();  
Assert.hasText(clusterNodes,  
"[Assertion failed] clusterNodes settings missing.");  
for (String clusterNode : split(clusterNodes, COMMA)) {  
String hostName = substringBeforeLast(clusterNode, COLON);  
String port = substringAfterLast(clusterNode, COLON);  
Assert.hasText(hostName,  
"[Assertion failed] missing host name in 'clusterNodes'");  
Assert.hasText(port,  
"[Assertion failed] missing port in 'clusterNodes'");  
// [logger.info](http://logger.info)("adding transport node : " + clusterNode);  
client.addTransportAddress(new InetSocketTransportAddress(  
InetAddress.getByName(hostName), Integer.valueOf(port)));  
}

but always encounter with the following error , which prevent tomcat to start normally!
