Hello Nadine,

thanks for your effort and your solution!

I already created and deleted product partitions in past, but I never had 
these problems before. I never recognized that the order in the request was 
relevant, I always thought it's sufficent to keep a consistent state after 
a request.

Therefore my question: was something changed on product partition's server 
side or have I just been lucky by not running into these problems so far? 
(I changed my task collector from List to Set so it's absolutely possible, 
that request's  operation order changed)
