> The following code fails from time to time (with a NPE since

> {noformat}
> strCmd = "sh bash -c 'touch TouchedFileInsideGrunt_61 | ls | grep
> TouchedFileInsideGrunt_61 > fileContainingTouchedFileInsideGruntShell_71'";
> cmd = new ByteArrayInputStream(strCmd.getBytes());
> reader = new InputStreamReader(cmd);
> grunt = new Grunt(new BufferedReader(reader), context);
> grunt.exec();
> fileReader = new BufferedReader(new
> FileReader("fileContainingTouchedFileInsideGruntShell_71"));
