in the BufferView class, the javadoc of setCacheSize says that default is 10, but in the variable initialization it's 20.

Code:
 private int cacheSize = 20;

...

  /**
   * Sets the amount of rows that should be cached (default to 10).
   * 
   * @param cacheSize the new cache size
   */
  public void setCacheSize(int cacheSize) {
    this.cacheSize = cacheSize;
  }
