Known Errors for JHOVE 1.0, 2005-05-26

• The HTML module will sometimes report incorrect line numbers for syntax errors if the file contains blank lines.
• The TIFF module incorrectly looks for the GeoTIFF ModelTransformationTag with a value of 34254, not its correct value of 34264.
• The TIFF module may incorrectly report a count mismatch for the ISOSpeedRatings tag of a TIFF/EP file.
• The TIFF module will report valid files as being only well-formed with an error message of the form: "Invalid DateTime separator: 2005-03-09T00:00:00". This message may be incorrect due to an error in handling the date string, which is being inappropriately converted to ISO 8601-form prior to being tested for format validity.
• The HTML may be caught in an endless loop if invoked against some non-HTML text files containing the "<" character.
• The AIFF module reports an incorrect value for the first sample offset in files with a non-zero offset field in the SSND chunk.
• The AIFF module reports bitrate reduction data for non-standardly encoded PCM audio.
• XML-encoded AES audio metadata is not valid relative to the schema because of badly formatted sample rates.
• The PDF module may report files with malformed date strings as being valid, and files with well-formed date strings with trailing whitespace as being invalid.
• The PDF module reports files with non-existent, indirect destination references as "non-well-formed", rather than "well-formed, but invalid".
• The JPEG module does not report the X and Y sampling frequency for files meeting the JFIF profile, nor does it report the pixel aspect ratio for JFIF profile files for which it is defined.
• When displaying text strings reported by various modules, the XML handler will include any control characters that appear in those strings. However, control characters other than TAB (0x09), CARRIAGE RETURN (0x0a), and LINE FEED (0x0d) are not allowed in well-formed XML.
• The "subMessage" attribute is not defined by the jhove.xsd schema.
• The PDF module throws a Class Cast Exception if the Info key of the trailer dictionary is not an indirect reference.
• The TIFF parser loses synchronization when reading a pyramidal TIFF file using the SubIFDs tag (330) with a type of IFD (13) rather than LONG (4).
• The TIFF module only reads the first sub-IFD of a pyramidal TIFF file.
• The XML module may terminate abnormally if a schemaLocation attribute does not properly define two whitespace-separated URIs, depending upon the SAX parser being used.
• The JPEG 2000 module may incorrectly identify files produced by the LuraWave codec as having unrecognized QCC marker segments.
• The PDF module reports the "IncrementalUpdate" property as the total number of file trailers, not the number of incrementally-updated trailers, which is one less than the total.
• The TIFF module does not properly parse the EXIF SubsecTimeOriginal (37521) or SubsecTimeDigitized (37522) properties. This bug also occurs for JPEG files containing EXIF metadata.
