    Description

      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.
