Subject [jira] Created: (RIVER-323) DynamicPolicyProvider - Concurrency
Date Tue, 03 Nov 2009 05:14:59 GMT
DynamicPolicyProvider - Concurrency
-----------------------------------

                 Key: RIVER-323
                 URL: https://issues.apache.org/jira/browse/RIVER-323
             Project: River
          Issue Type: Improvement
          Components: net_jini_security
         Environment: All
            Reporter: Peter Firmstone
            Priority: Minor


>From the river-dev mail list:

I have been looking into some seemingly slow responses in several clients running simultaneously,
and I see in some stack traces that there are synchronization points in DynamicPolicyProvider.implies()
that seem to be heavily contended.  We probably need to revisit this class and rewrite it
to use copy on write mutation so that reads (the majority of activity) are completely uncontended.

Any thoughts or experience with this issue?
