MapSession uses a HashMap internally, but it does not have any synchronization. This means it is not safe for multiple requests to access the same MapSession object at the same time.
In particular, when fetching a session from the repository, AbstractInfinispanSessionRepository.getSession() wants to update the TTL of the session, which requires updating the session in the cache. If another thread is modifying the session at the same time, the MapSession serialization fails with a ConcurrentModificationException.

The serialization error then leads to ISPN-12435, because the AckCollector created by TriangleDistributionInterceptor is not released.
