subclasses can override it:

https://github.com/qos-ch/logback/blob/master/logback-core/src/main/java/ch/qos/logback/core/rolling/FixedWindowRollingPolicy.java

/**
    * Subclasses can override this method to increase the max window 
size, if required.  This is to
    * address LOGBACK-266.
    * @return
    */
   protected int getMaxWindowSize() {
     return MAX_WINDOW_SIZE;
   }

or probably you just need
