the file below seems to indicate a problem with datainputStream.readLine's handling of EOF conditions. Contact ###@###.### for more information.

Runtime runtime;
Process process;

line=new String();

try {

}
catch (IOException e) {
System.out.println("IOException doing exec.");
return;
}

dinputStream = process.getInputStream();
bufferedInputStream = new BufferedInputStream(dinputStream);

do {
try {
line = dataInputStream.readLine();
     }

catch (IOException e) {
System.out.println("IOException doing readLine.");
   line = null;

}
if (line != null) {
System.out.println(line);
}
} while (line != null);
