Andrea Ligios commented on WW-4457:
-----------------------------------
It doesn't seem to work; I've tested my code with this struts2-core 2.3.22
SNAPSHOT:
https://repository.apache.org/content/groups/snapshots/org/apache/struts/struts2-core/2.3.22-SNAPSHOT/struts2-core-2.3.22-20150307.084404-13.jar
and all the other struts jars on 2.3.16.3.
The behaviour is the same of 2.3.16.3:
"image/svg\\+xml" works,
"image/svg+xml" doesn't.
> FileUploadInterceptor uses injected pattern matcher

> Key: WW-4457
> URL: https://issues.apache.org/jira/browse/WW-4457
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Reporter: Aleksandr Mashchenko
> Assignee: Lukasz Lenart
> Fix For: 2.3.22
>
>
> Currently {{FileUploadInterceptor}} uses injected pattern matcher for
> checking {{allowedTypes}}, which yields inconsistent behavior with different
> default pattern matchers. Some mime types which are working fine with
> {{WildcardHelper}} are not working with the {{RegexPatternMatcher}}, because
> of the special regex character presented in them (e.g. {{image/svg+xml}} -
> {{+}} is a special character in regex).
> IMO file upload interceptor should use {{WildcardHelper}} no matter what
> pattern matcher is set as the default one. Or is there any point in injecting
> pattern matcher in file upload interceptor?
> Original report: [“Content-Type not allowed” while uploading an SVG file,
> that is in the allowed whitelist|http://stackoverflow.com/q/28304692/1700321]
