ConnectionCount logic does not produce a sensible ConnectionFactory max pool size for some scenarios

   public int getConnectionCount(int max, ConnectionType type) {
        Reject.ifTrue(max < MINIMUM_CONNECTIONS);
        switch (type) {
            case CTS_ASYNC:

                    max = max / 2;
                } else {
                    max = max - 2;
                }
                return findPowerOfTwo(max);
            case CTS_REAPER:
                return 1;
            case DATA_LAYER:
                /**

                  * connection space alongside CTS_REAPER and CTS_ASYNC
                  */
                int async = getConnectionCount(max, ConnectionType.CTS_ASYNC);
                int reaper = getConnectionCount(max, ConnectionType.CTS_REAPER);
                return max - (async + reaper);
            default:
