[jboss-jira] [JBoss JIRA] Commented: (JBCACHE-1304) OrderedSynchronizationHandler not thread safe

[Manik Surtani (JIRA)]

    [ http://jira.jboss.com/jira/browse/JBCACHE-1304?page=comments#action_12401798 ] 
            
Manik Surtani commented on JBCACHE-1304:
----------------------------------------

Resolved: OSH has no static variables anymore; instead it is instantiated when a TransactionEntry is created and the ref is stored in and obtained from the TransactionEntry, rather than the factory method on OSH.

> OrderedSynchronizationHandler uses a static Map to hold instances referenced by a Transaction object, and the factory method on the OSH uses this map to retrieve instances.
> 1)  This map is unguarded and hence not thread safe.
> 2)  The map is static, which means it is shared across all cache instances in a given JVM.  Not intended to work this way.
