        Description

        CryptoPermissions uses Hashtable as internal collection.
        Lock contention on the Hashtable broke scalability.
        Patch is suggested, where ConcurrentHashMap is used.
        The attached webrev.zip contain suggested patch.

        Gives +12% to SPECjbb2012(encrypted transport) on T4-4.
