EXTRA RELEVANT SYSTEM CONFIGURATION :

A DESCRIPTION OF THE PROBLEM :
When a KeyEvent Listener is fired on the enter key, my program switches scenes on a Stage from JavaFX. I can switch to the alternate stage, and then back, but the next time KeyEvent is fired, (for a non-enter key) the program crashes and Eclipse reports a Fatal Error detected by the JRE (SIGSEGV (0xb) at pc=0x0000000122ae6536)
According to this, the "crash happened outside the Java Virtual Machine in native code."
