expect a command like 'getstatic', can get non-static field from a singleton object

public class Singleton {
    private Singleton singleton = new Singleton();
    private String test = "abc";

    private Singleton() {}

    public Singleton getInstance() {
         return singleton;
    }

}

Expected command:

getstatic -c hash_code Singleton getInstance '{returnObj.test}'

Expected output:

abc

Is this what you want? If so, this is currently not supported yet.

[Kingson4Wu]

yes，this is what I want.
If there is only one object in JVM, the parameter 'hash_code' is not nesscessary?

[ralf0131]

@hengyunabc I believe this feature has not been implemented yet. Currently getstatic command does not support expression. We should leave it open.

@Kingson4Wu Yes

@ralf0131 What's the best way to make sure it's a singleton:

• private constructor

enough? #230

Refer to #240
