Imesha,
I can't comment particularly this piece of code. The initial
question was too general and I thought about QueueConsumer, for example,
or other type of listener that is implemented by customer and executes
customer code.
It might be some type of dependency for that function that could
depend from customer code. If you want to go deeper - you can analyze
source and check if there are such. May be there is no reason for that
also. :)
