> Parser Order: image get parsed by GDALParser instead of TesseractOCRParser
> --------------------------------------------------------------------------
>
> Key: TIKA-3812
> URL: https://issues.apache.org/jira/browse/TIKA-3812
> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 2.4.1
> Reporter: Eugen Caruntu
> Priority: Minor
> Fix For: 2.4.2
>
>
> The selected parser seems to be different in 2.4.1. For example sending an image (jpg/png) that was previously (2.4.0) processed by TesseractOCRParser, now gets parsed by GDALParser.
> Seems that when multiple parsers support same file types, the selected parser depends on the order in which they get loaded.
> For example the GDALParser, ImageParser and TesseractOCRParser all support image/jpeg, image/png, image/gif ...
> A recent change is reversing the parser order (TIKA-3750).
> Re-configuring the GDALParser by excluding the image mime types might work, but there could be other duplicated parsers.
