> Environment: Java 8

> Hello!
> If I read an input stream until end of it, and then read it again, it throws
> an exception.
> Here is the test case:
> {code:java}
> BufferedReader input;
> String line;
> //process.getInputStream() gets its value from
> ChannelExec#getInvertedOut()
> System.out.println("getInputStream: " + process.getInputStream());
> input = new BufferedReader(new
> InputStreamReader(process.getInputStream()));
> while ((line = input.readLine()) != null) {
> System.out.println(line);
> }
> System.out.println("getInputStream: " + process.getInputStream());
> input = new BufferedReader(new
> InputStreamReader(process.getInputStream()));
> while ((line = input.readLine()) != null) {
> System.out.println(line);
> }
> {code}
> Here is an output excerpt:
> {quote}getInputStream:

> It looks the input stream is closed.
> is it possible not to throw an exception to rely on java.io.InputStream ?
> Thanks in advance...
