[jira] [Updated] (TIKA-2608) tika matlab parser incorrectly identifies content type of minified javascript file

     [ https://issues.apache.org/jira/browse/TIKA-2608?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

pdwalker updated TIKA-2608:
---------------------------
    Description: 
When the tika "detects" the following file, it returns the wrong content type:

{{$ curl -I [https://wiki.charltonslaw.com/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.min.js]}}
 {{HTTP/1.1 200 OK}}
 {{Server: nginx/1.10.3 (Ubuntu)}}
 {{Date: Fri, 16 Mar 2018 10:09:54 GMT}}
 {{Content-Type: text/x-matlab}}
{{  [snip]}}
{{X-Frame-Options: SAMEORIGIN}}

However, the unminified version of the same file returns the correct type:

{{$ curl -I [https://wiki.charltonslaw.com/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.js]}}
 {{HTTP/1.1 200 OK}}
 {{Server: nginx/1.10.3 (Ubuntu)}}
 {{Date: Fri, 16 Mar 2018 10:10:25 GMT}}
 {{Content-Type: application/javascript}}
{{  [snip]}}
{{X-Frame-Options: SAMEORIGIN}}

The problem this causes is when my xwiki installation is behind an ssl proxy (nginx) and I enable the add_header X-Content-Type-Options nosniff; header.  

Modern browsers return the following error:
{quote}Refused to execute script from '[https://wiki.charltonslaw.com/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.min.js|https://wiki.proxy.domain/xwiki/webjars/wiki%3Ait/mxgraph-editor/3.7.2/mxGraphEditor.min.js]' because its MIME type ('text/x-matlab') is not executable, and strict MIME type checking is enabled.
{quote}
My "solution" is to disable the strict mime type checking in the ssl proxy, but I don't think that is idea.  It'd be better of the matlab parser didn't claim random minified js files as its own.
