java - New Jedis Client Does Not Work In Static Java Method

Question

Why does this same piece of code have different results?

I'm using Jedis 2.1.0 to create connections to Redis.

METHOD A:

private static Jedis getNewJedis() {
        return new Jedis(hostname,port);
    }

.....
public static main(String[] args){
     getNewJedis().ping();
}

METHOD B:

public static main(String[] args){
     new Jedis(hostname,port).ping();
}

I'm thinking the difference is Method A has been tucked away in a static method for ease of reuse, and hence should have the same effect as Method B when invoked.

Instead, I get an exception when I use Method A. Method B works fine!

METHOD A Exception:
