Resolved System.out.println randomly blocks

I've come across an interesting bug, I'm not sure if it's java or the client but every so often System.out will start blocking:

Code (Text):

1. status = "Mushroom";
2. System.out.println("test");
3. status = "Pineapple";

This code will result in the status being set to Mushroom, and the script bot hanging (the pineapple line is never touched).

Again, I don't know if this a client or a java issue, all I know is that it happens every now and then.

I usually get this after printing a massive amount of lines to the console. I think it might just be an issue with Windows 10 though, since I can solve it by resizing the cmd window. On a resize it prints everything that it had buffered.
