-----------------------------------
Summary: Fix: Concurrent Modification Exception in InMemorySystem
Key: SAMZA-2461
URL: https://issues.apache.org/jira/browse/SAMZA-2461
Project: Samza
Issue Type: Bug
Reporter: Yixing Zhang
The returned value of InMeomoryManager#poll is a sublist of a mutable list.
While iterating the sublist, if the original list is modified,
ConcurrentModification exception will be thrown. We need to make a copy of the
sublist and return the copy instead.
