Wildfly return 403 forbidden page after accessing a nonexistence page

[Hiep Thai]

Hello everyone

I am running Wildfly version wildfly-14.0.1.Final, and geting 403 forbidden page after accessing a nonexistence page .

For detail:

1. Access a nonexistence page  Ex:"localhost:8080/mysite/test"

   -> get 404 error because no resource 'test'

2. Upload folder 'test" that have "index.html" (without re-deployment) on 'mysite'

3. Access "localhost:8080/mysite/test" again

   -> get 403 forbidden error

But access "localhost:8080/mysite/test/" or "localhost:8080/mysite/test/index.html" -> it works.

It seem that is a bug of Wildfly.

Does anyone have idea ?

Thanks !!!
