[yuhui2016github]

Description

does not support shadow Thread.class

Steps to Reproduce

@Implements(Thread.class)
public class ShadowThread extends Thread {

    @RealObject
    private Thread thread;

    @Implementation
    public synchronized void start() {
        System.out.println("========Thread start ======");
        thread.run();
    }
}

@Config(manifest = "src/main/AndroidManifest.xml", shadows = {MyShadowHandler.class, ShadowThread.class})
public Class .... {

....
@Test
    public void onNetworkAvailable() throws Exception {
        Thread thread = new Thread();
        thread.start();
}
}

it does not run into ShadowThread.start() method, I have another shadowHandler class which can work,

Robolectric & Android Version

org.robolectric:robolectric:3.3.2

Robolectric doesn't support shadows for classes under the java. package unfortunately.
