i'm having a hard time finding a single instance of ListenerList class 
(i'm running under a profiler) 
in which the list would contain more than 1 element

so the other 2 are almost always wasted
because this class is instantiated many, many times (i just started and see 
more than 1300 instances) the default size should be 1. 
It can then grow if necessary.

see bug 27108 - this class is copied from Workbench

Note that the other copies are in JDT Core.
UI components should just use the one in JFace.

closing this one - it was the jface ListsnerList that was the problem
one bug 27938 is fixed we will be able to have just 1 ListenerLists class
