See Jira ticket for full context. In summary: * HashMap#putAll on a synchronizedMap is *not* thread-safe. It will access `.entrySet().iterator()` internally, allowing it to cause a `ConcurrentModificationException`. * This PR simply synchronizes on the data so the iterator call remains safe. *Note*: ConcurrentHashMap does not work here because it does not allow `null` values. -- This is an automated message from the Apache Git Service.
