/**
 * This exception will be thrown if a request is made to a node, relationship or
 * property that does not exist. As an example, using
 * {@link Transaction#getNodeById} passing in an id that does not exist
 * will cause this exception to be thrown.
 * {@link Entity#getProperty(String)} will also throw this exception
 * if the given key does not exist.
 * 
 * Another scenario involves multiple concurrent transactions which obtain a reference to the same node or
 * relationship, which is then deleted by one of the transactions. If the deleting transaction commits, then invoking
 * any node or relationship methods within any of the remaining open transactions will cause this exception to be
 * thrown.
