> Resetting the BOMInputStream doesn't reset the _fbLength_ member variable. This causes _fbLength_ to grow bigger than the _firstBytes_ array (when the file doesn't contain a BOM), which leads to an ArrayIndexOutOfBoundsException in the _readFirstBytes_ method.
> The attached test case reveals the problem.
