The error info

> Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.elasticsearch.client.transport.TransportClient]: Factory method 'elasticsearchClient' threw exception; nested exception is java.lang.IllegalStateException: availableProcessors is already set to [4], rejecting [4]

And I add "System.setProperty("es.set.netty.runtime.available.processors", "false");"  
`public static void main(final String[] args) {`  
`System.setProperty("es.set.netty.runtime.available.processors", "false");`  
`SpringApplication springApplication = new SpringApplication(Application.class);`  
`springApplication.addListeners(new ApplicationPidFileWriter("sns.pid"));`  
`springApplication.run(args);`  
`}`

It works in my local enviroment(oracle jdk1.8), but does not work in server  
enviroment(openjdk1.8).  
I am not sure whether the jdk version matters? If not, how to solve the error?Thanks.

OS: Centos

Finally I added the parameters in the start bash, and it worked.

> -Des.set.netty.runtime.available.processors=false

I thought that the main function code 'System.setProperty("es.set.netty.runtime.available.processors", "false");' should be loaded first.
