[~nick] Thanks. Note that it seems to be some sort of regression since it worked fine before the upgrade to Tika 2.0.0. Was this change of behavior wanted?

>             Project: Tika
>          Issue Type: Bug
>          Components: detector

> The following CSS file [https://github.com/techlab/jquery-smartwizard/blob/v5.1.1/dist/css/smart_wizard_all.min.css] is detected as {{application/javascript}} using:
> {noformat}
> TikaUtils.detect(InputStream stream, String name)
> {noformat}
> The reason seems to be that the CSS file starts with:
> {noformat}
> /*!
>  * jQuery
> {noformat}
> which matches the "jQuery" entry from [tika-mimetypes.xml|https://github.com/apache/tika/blob/2.3.0/tika-core/src/main/resources/org/apache/tika/mime/tika-mimetypes.xml#L348] used by Tika's {{MimeTypes}} detector.
> This is a regression introduced by https://github.com/apache/tika/commit/97699598f000139b1222b785d634b3c8a8e216c7 in TIKA-1141 (2.0.0-ALPHA).
> The implications are serious if the mime type returned by Tika is used to set the content type on the HTTP request returning the CSS file to the browser: the browser ignores the CSS.
> FTR, in my case the CSS file is not served directly from the file system but from a WebJar (in this case https://search.maven.org/artifact/org.webjars.npm/smartwizard/5.1.1/jar ) and we're using Tika to determine the type of files requested from the WebJars.
