[jira] Commented: (JS2-597) Concurrency issue in DatabasePageManger
cache
[ http://issues.apache.org/jira/browse/JS2-597?page=comments#action_12441204 ]
David Sean Taylor commented on JS2-597:
---------------------------------------
Im in the process of replacing all ArrayLists with RemovalAwareCollection/Lists
I haven't seen the error you are having, but it might help if OJB synchronizes its collections
sorry, i didn't finish last night, hope to finish this today
