[ https://issues.apache.org/jira/browse/QPID-1972?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aidan Skinner resolved QPID-1972.
---------------------------------
Resolution: Fixed
I've applied Julien's patch from QPID-1987
> UUID.randomUUID() is not thread-safe
> ------------------------------------
>
> Key: QPID-1972
> URL: https://issues.apache.org/jira/browse/QPID-1972
> Project: Qpid
> Issue Type: Bug
> Components: Dot Net Client
> Affects Versions: M3, M4, 0.5
> Environment: .net API
> Reporter: Julien Lavigne du Cadet
> Priority: Critical
> Fix For: 0.6
>
>
> UUID.randomUUID is not thread-safe because it's using a static random object.
> However, recreating a random object each time the method is called is not an option because 2 successive calls might result in the same UUID.
> Please find attached in the next comment a patch that fixes the issue by introducing a UUIDGenerator class. Now, to get a random UUID, you first need to instantiate a UUIDGenerator and request it through it. That way there's no need to lock in the UUID class.
> Please note that this patch is BREAKING COMPABILITY with previous versions of the API !
> The patch is also fixing 2 others issues :
> - test.config is not included in the unit test project which result in half of the unit tests failing
> - the management console is not compiling with vs 2008 and .Net 2.0
