Spring-Batch MongoDB : Skip functionality is not working properly in MongoItemReader scenario - spring

Question

Skip exception class functionality is not working properly when MongoItemreader is being used.
Issues:
1. Spring batch is stuck at a particular data row (in my case 15). It calls MessageContextReadConverter and onReadError for same row number 15 -- 3 times.
2. skiplistener is never invoked.
Scenario:
Suppose 20 rows are fetched from MongoDB and at row number 15 configurable exception ".ConversionFailedException" is thrown from a custom class derived from Converter, (MessageContextReadConverter implements Converter)
. MessageContextReadConverter is set during mongoTemplate creation,.
Now, exception thrown at row number 15 is received in custom readlistener (public void onReadError(Exception ex)).
