EAP 7 returns 404s for any static content served from a directory starting with WEB-INF or META-INF

Environment

• JBoss Enterprise Application Platform (EAP) 7.x

Issue

• Our application serves static content from some directories that start with WEB-INF or META-INF (such as WEB-INFOOBAR or META-INFOOBAR). After moving to EAP 7, we now get 404s for any of this content. This worked previously on EAP 6 or Tomcat.

Resolution

• Upgrade to EAP 7.4.1+

Root Cause

• This content is not included.UNDERTOW-1898
• This content is not included.JBEAP-22026
• This content is not included.JBEAP-22025
• The DefaultServlet is preventing exposure of any content from WEB-INF or META-INF but this goes too far and blocks content from any directory name starting with those strings.
