Subject [jira] Updated: (HARMONY-5829) [drlvm][kernel][performance] j.l.Class Serializable/Externalizable caching
Date Thu, 15 May 2008 20:06:55 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-5829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Aleksey Shipilev updated HARMONY-5829:
--------------------------------------

             Component/s: DRLVM
    Estimated Complexity: Novice
             Description: Serialization workloads relies on Class.isAssignableFrom(...) when
looking up Serializable and Externalizable properties (that is, implementation of interfaces).
For now, DRLVM kernel classes perform lookups on each invocation. This issue caches the mentioned
properties in Class fields and does not go to native VMClassRegistry for resolution.
              Patch Info: [Patch Available]
