      Description

        Initial benchmarks show a significant increase in throughput of the PermissionCollection.implies method when concurrent collections are used to store permissions (instead of using synchronized blocks to synchronize access to non-concurrent collections). This applies to the PermissionCollection subclasses implemented in SocketPermission, FilePermission, etc.
