OpModelRoot#refreshModel() is calling Oprofile.getEvents(). The getEvents() 
call returns an empty array, therefor (I guess) nothing is shown. Some where 
down, "opxml sessions" is executed. This is returning an empty list too, but 
(I guess) it shouldn't?

<?xml version="1.0" encoding="UTF-8"?>
<sessions>
</sessions>
