Thread.interrupt doesn't work for InputStream.read(). This is related to bug
#4344135, but doesn't involve closing of an underlying socket.
The program below shows that the thread cannot be interrupted.

The program works fine under Solaris 8 Update 5 with JDK 1.3.1.



import java.net.*;

/** Tests Thread.interrupt() against InputStream.read() */
public class test2 {

    static class SleeperThread extends Thread {
public void run() {
int c;
try {
c=System.in.read();
}
catch(Exception ex) {
System.err.println("test2.SleeperThread.run(): " + ex);
}
}
    }

    
    public static void main(String[] args) {
Thread thread;
final long TIMEOUT=3000;

thread=new SleeperThread();
thread.start();
System.out.println("test2.main(): sleeping for " + TIMEOUT + " msecs");
try {thread.sleep(TIMEOUT);} catch(Exception e) {}
System.out.println("test2.main(): sleeping -- done");

System.out.println("test2.main(): interrupting thread");
thread.interrupt();
System.out.println("test2.main(): interrupting thread -- done");

System.out.println("test2.main(): joining thread (timeout=" + TIMEOUT + "
msecs)");
try {thread.join(TIMEOUT);} catch(Exception e) {}
System.out.println("test2.main(): joining thread -- done");

System.out.println("test2.main(): thread.isAlive()=" + thread.isAlive());
if(thread.isAlive()) {
System.out.println("test2.main(): thread was interrupted but is still
running !");
}
    }
}
