Tim Allison commented on TIKA-1689:
-----------------------------------
[~dwarren], thank you for raising this.
[~chrismattmann] and [~Lukeliush], this seems like a pretty serious change in
the API, no?
> Parser sort order change in TIKA-1517 breaks parser override capability
> -----------------------------------------------------------------------
>
> Key: TIKA-1689
> URL: https://issues.apache.org/jira/browse/TIKA-1689
> Project: Tika
> Issue Type: Bug
> Components: core
> Affects Versions: 1.9
> Reporter: David Warren
>
> In Tika 1.9, the comparator used to sort parsers (in ServiceLoaderUtils) now
> returns them in the reverse order from how they were returned in prior
> versions, when the comparator was in DefaultParser. This work was done under
> TIKA-1517.
> This change broke one of our customizations in which we use our own parser
> instead of Tika's HtmlParser to process html. We use the service loader
> logic (creating our own META-INF/services/org.apache.tika.parser.Parser file)
> and rely on the order in which the list returned by
> DefaultParser.getDefaultParsers() is evaluated. Expecting that when Tika
> builds the map of mime types to parsers it first puts in entries for
> HtmlParser, then overwrites these with our custom parser.
> I realize relying on this is brittle. And I found a valid workaround to the
> problem in Tika 1.9 is to blacklist HtmlParser. However, in case this parser
> ordering change was not intentional, I figured I'd mention it.
