I am trying to run external program using JavaProcessBuilder class. This program doesn't any status ( it freeze here: int status = mosesPro.waitFor();) when there are more than 20 lines in my test file (argument with -input-file). I would be very thankful for any solution/suggestion. I have attached my sample code below:

			

			String command [] = new String [5];
			

			command [0] = "/Users/X/tools/moses/moses-cmd/src/moses";
			

			command [1] = "-config";
			

			command [2] = "/Users/X/Documents/thesis/workspace/juneTest/translation/evaluation/filtered.test/moses.ini";
			

			command [3] = "-input-file";
			

			command [4] = "/Users/X/Desktop/test2.input";
			

			try {
			

			child = new ProcessBuilder(command);
			

			mosesPro = child.start();
			

			int status = mosesPro.waitFor();
			

			if (status == 0) {
			

			BufferedReader reader = new BufferedReader(new InputStreamReader(mosesPro.getInputStream(), "UTF-8"));
			

			String line;
			

			line = reader.readLine();
			

			while (line != null) {
			

			System.out.println(line);
			

			line = reader.readLine();
			

			}
			

			reader.close();
			

			

			} else {
			

			BufferedReader errorReader = new BufferedReader(new InputStreamReader(mosesPro.getErrorStream(), "UTF-8"));
			

			String errLine;
			

			errLine = errorReader.readLine();
			

			while (errLine != null) {
			

			System.out.println(errLine);
			

			errLine = errorReader.readLine();
			

			}
			

			errorReader.close();
			

			

			}
			

			mosesPro.destroy();
			

			

			} catch(Exception ex) {
			

			ex.printStackTrace();
			

			}
