Writing commands to BungeeCord Process OutputStream does not appear to execute them

Here is the code I am using to read / write to a BungeeCord process. Only issue is it appears that writing commands to the output stream does not appear to work.

I believe my code is working correctly for the following reasons:

• I have checked that that the code that writes to the output stream is being reached with the correct command
• This code works flawlessly using the Spigot server jar.

Fixed by disabling JLine in command arguments.
