Hello,

My Java application need to invoke rxvt. On Windows XP rxvt window 
appears and works fine. On Windows 7 the window does not appear, while I 
can see rxvt.exe in the list of running processes. Launching rxvt.exe 
from Start/Run, from Explorer, and from cmd.exe shell all work fine too, 
so the problem appears only if rxvt.exe is called from Java application...

Below is a very short example which can be used to reproduce the problem:

-----------------------------------------------------------------------------
import java.io.IOException;
public class Main {
     public static void main(String[] args) throws IOException, 
InterruptedException {
         Runtime runtime = Runtime.getRuntime();
         System.err.println("executing");
         Process process = runtime.exec("c:\\cygwin\\bin\\rxvt.exe");
         System.err.println("exec done, waiting ...");
         process.waitFor();
         System.err.println("wait done");
     }
}
-----------------------------------------------------------------------------

1) save as Main.java
2) compile it:
     javac Main.java
3) run it:
     java Main


The problem appears in Windows 7 64 bit, latest Cygwin and Sun JRE:

$ uname -a
CYGWIN_NT-6.1-WOW64 w7 1.7.7(0.230/5/3) 2010-08-31 09:58 i686 Cygwin

Z:\home-tmp\JavaApplication4\dist>"c:\Program Files 
(x86)\Java\jre6\bin\java.exe
" -version
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)


Any idea why this can possibly happen? fixes/workarounds? Thank you.

Best regards,
