Subject [jira] [Updated] (QPID-3319) org.apache.qpid.server.subscription.SubscriptionList leaks memory
Date Wed, 29 Jun 2011 07:45:28 GMT

     [ https://issues.apache.org/jira/browse/QPID-3319?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Srinath Perera updated QPID-3319:
---------------------------------

    Attachment: QPID-3319.2.patch
                QPID-3319.3.patch
                QPID-3319.patch

I worked with this on Danushka, and the following fix worked for us. We have done pretty intensive
testing and believe this fixes the problem. 

Here I am removing the subscription list impl and implementing it using ConcurrentLinkedQueue
while keeping the interface intact as much as possible. the java concurrent implementation
of the queue. 

QPID-3319.patch has the fix and QPID-3319.patch.2 and QPID-3319.patch.3 fix two other classes
that cause a compilation error when the QPID-3319.path is applied.
