A DESCRIPTION OF THE PROBLEM :
I am using a LinkedList in a thread. Often when removing (LinkedList.removeFirst()) an object from the LinkedList an exception is thrown. The error is shown below. I have verified that the LinkedList is not empty when trying to remove an object.

Exception in thread "Thread-0" java.util.NoSuchElementException
at java.util.LinkedList.removeFirst(LinkedList.java:270)
at Mediator.run(simRaymond_mod_20151029.java:212)

REPRODUCIBILITY :
This bug can be reproduced often.

CUSTOMER SUBMITTED WORKAROUND :
I have tried changing the LinkedList to an ArrayList but that hangs often as well. It will not always throw an exception but it will hang.
