How to run CMD commands from springboot service?

I'm able to run same code through a normal java class. However when I move same code to a service class in springboot, and call the service from controller on a hit of url, the command doesn't run or gets stuck for a long time. 

    Process process = new ProcessBuilder("CMD", "/C", command2).start();
    .
    .
    .
    process.waitFor();
    process.destroy();

Tried a lot of times and different ways, still not able to find the solution.

command is 

"tool --f pathToFile".

Try to use separate arguments and dont use entire command but break it into separate argumennts as below:

try {
            List<String> commands = new ArrayList<>();
            commands.add("CMD");
            commands.add("/C"); 
            commands.add("tool");
            commands.add("--f");  
            commands.add(pathToFile);
            ProcessBuilder pb = new ProcessBuilder(commands);
             try {
                    Process p = pb.start();
                    int j = p.waitFor();
                    int exitValue = p.exitValue();
                    System.out.println("Finished with code: " + j);
                    System.out.println("Finished with exitValue: " + exitValue);
                } catch (Exception e) {
                    System.out.println("exception: " + e);
                }
        } catch (Exception e) {
            e.printStackTrace();
        }
