when you use the standard beans.xml schema location in your beans.xml (referencing http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd) then WELD tries to look it up on the internet.  Oracle has had some technical issues with their web servers and returns an html error page when accessing the URL, leading to applications failing to deploy with:
