[jira] Issue Comment Edited: (EXEC-33) PumpStreamHandler hangs if

----------------------------------------------------------------
Confirmed so far ...
+) the following test script hangs
+) one worker thread stll hang in StreamPumper.java
+) Having said this I have a working test case for redirecting a FileInputStream instead of System.in so I'm a bit pussled
{noformat}
/**
* Start a process and connect stdin, stdout and stderr. This
* test currenty hang ....
*/
public void testExecuteWithStdin() throws Exception
{
CommandLine cl = new CommandLine(testScript);
PumpStreamHandler pumpStreamHandler = new PumpStreamHandler( System.out, System.err, System.in );
DefaultExecutor executor = new DefaultExecutor();
executor.setStreamHandler( pumpStreamHandler );
int exitValue = executor.execute(cl);
assertFalse(exec.isFailure(exitValue));
}

> When process input is redirected using a PumpStreamHandler, e.g.
> PumpStreamHandler streamHanlder = new PumpStreamHandler(out, err, System.in);
