While that is good to know, you still haven't answered my initial 
question:

>> On which line do you get the Exception?

If your program terminates because of an uncaught exception (as 
you stated), then you should've received a stack trace containing 
the line number on which the exception was thrown (remember to 
compile with debug info).
You should also consider providing a compilable, minimal example 
(with test data) that can be used to reproduce the issue.
