Can you use multiple proxies at once in java?

I'm coding my server in java, and through the day, my server has to connect through 5 different proxies at once to other servers and gather data. However, reading about java proxy settings through stackexchange, I see that when you set a proxy, its effect is VM-wide, meaning whatever network activity that .jar was doing, it will do it through a proxy if somewhere a different thread sets a proxy setting within the jar.

I'm currently using this method of setting a proxy, which according to some tests it's actually pretty functional and works fast. 

    System.getProperties().put( "http.proxyHost", host );
    System.getProperties().put( "http.proxyPort", port );

However, I can't really afford having 5 jars doing the same thing with different proxies, I tried it to, it would be a simple solution however I can't afford to use that much ram only for this, as my server is huge.

here is described the use a library embeded in the JRE, able to handle "proxypac" files in wich any combination of proxies can be defined.

since it is embeded in the JRE, standard ways to configure a Java application with a proxypac file (standard launch optional parameters) might exist, but I am not aware of it.

Howhever the solution described in the link provided should fit your needs since your usage is programatic.

You need to call each connection with its own proxy settings. The Answer here by NickDk defines how you can call a url with its own proxy settings. You will need to do the same with each of your 5 proxies separately.
