[infinispan-issues] [Red Hat JIRA] (ISPN-12739) Spring Session Repository should create a copy of the MapSession for each request

Dan Berindei created ISPN-12739: ----------------------------------- Summary: Spring Session Repository should create a copy of the MapSession for each request Key: ISPN-12739 URL: https://issues.redhat.com/browse/ISPN-12739 Project: Infinispan Issue Type: Bug Components: Spring Integration Affects Versions: 12.0.1.Final, 11.0.9.Final, 9.4.21.Final Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 12.1.0.Final {{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}}. {noformat} 04:46:25.758 ERROR o.i.r.r.RpcManagerImpl -
