I have a java project and it executes rightly. But, when I put my code inside of a loop to execute it several times(e.g. 20 times) after some rounds it throws me this error:
As this project is a big one and I don't know in which line this error is happening I cant copy the code here.
So, Can you tell me when usually this error happens? or probably what can cause this sort of problems? or how can I find where in my code this is happening?
