Reading Events from CSV file into ESPER with POJO - csv

Question

Reading Events from CSV file into ESPER with POJO, the code below seams to scan through the file (larger files take longer), however no output is generated by events reaching listener.
the CSV file content is:
Geotimestamp,closeoutBid,closeoutAsk,tradable
"20170301 000000643",1.236550,1.236680,0
"20170301 000001893",1.236540,1.236680,0
"20170301 000002893",1.236550,1.236680,0
"20170301 000004410",1.236560,1.236700,0
"20170301 000006160",1.236540,1.236680,0
"20170301 000006393",1.236540,1.236670,0
The code is based on article here
