Command Line API Error

[ShivamP63]

Hi I was trying to use command line API and I got this error.

I am running this code on Java 10. I was able to successfully create a vocabulary file. But when I try to train the model and write to counter file , I got the error shown above. I tried upgrading to latest Java but got the same error.

Is there any solution to this issue that you can suggest ?
