After rollback, StoreDataManager no longer thread-safe

Created: 21/May/10 05:37 AM   Updated: 11/Jun/10 01:38 PM   Resolved: 21/May/10 06:42 AM
Component/s: Datastore Support
Affects Version/s: 2.1.0.m3
Fix Version/s: 2.1.0.release

 Description  « Hide
The StoreDataManager.storeDataByClass field is a ConcurrentHashMap, however during a transaction the backup that is taken of this field (savedStoreDataByClass) is a HashMap. In case of a rollback, storeDataByClass will then be assigned to that HashMap, and future operations may no longer be thread-safe.

StoreDataManager changed to ensure ConcurrentHashMap always used.
