Your application quit because an uncaught
RuntimeException was thrown.

I have found the stack trace, now what?
Yay! You're halfway to solving your problem.
You only need to find out what exactly made your application crash, by analyzing the stack trace.
Read up on stack traces in "What is a stack trace, and how can I use it to debug my application errors?"
I still can't solve my problem!
If you've found your
Exception and the line where it occurred, and still cannot figure out how to fix it, don't hesitate to ask a question on StackOverflow.
Try to be as concise as possible: post the stack trace, and the relevant code (e.g. a few lines up to the line which threw the
