UnsupportedFormatException is a subclass of  TikaException. This exception is thrown by parsers when a file format does not support it. It happens generally when based on MIME type not able to differentiate versions.

For Example: When writing mime type as application/perfect covers all versions of WordPerfect format while parsers only support 6.x only.

Solution

To handle such cases whenever possible distinguish file formats by specific MIME Type so that if any unsupported version finds out that will take care by EmptyParser. Even if not able to distinguish by MIME Type use the distinguish versions.
