@bchristi-git showed me this test. You might try it on other objects:

import org.ietf.jgss.GSSManager;
import org.ietf.jgss.GSSName;

import java.util.WeakHashMap;

public class A1 {
    private static WeakHashMap whm = new WeakHashMap();
    public static void main(String[] args) throws Exception {
        System.setProperty("sun.security.nativegss.debug", "true");
        System.setProperty("sun.security.jgss.native", "true");
        GSSName e = GSSManager.getInstance().createName("u1", GSSName.NT_USER_NAME);
        whm.put(e, null);
        e = null;
        for (int i = 0; i < 10; i++) {
            System.gc();
            Thread.sleep(100);
        }
        if (whm.size() > 0) {
            throw new RuntimeException("GSSElementName still reachable");
        }
    }
}
