Use ConcurrentHashMap to map ProtectionDomain to PermissionCollection

    XMLWordPrintable

Details

    Backports

      Description

        The current implementation uses a Collections.synchronizedMap. Replacing that with a ConcurrentHashMap (with additional code to remove weak keys) increases the throughput of the Policy.implies method by approximately 3x.
