Import of Maven projects which has web.xml version set to 3.0 does not work.
When changing version to 2.5, import works fine.

Steps to reproduce:

Does not work:
1. git-clone git@github.com:richfaces/dev-examples.git
2. Import > Existing Maven Projects
3. select dev-examples/input-demo and finish import
FAIL: WTP and Maven integration facets are not active

Works:
1. edit dev-examples/input-demo/src/main/webapp/WEB-INF/web.xml
2. change web-app version="2.5" and xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
3. delete project specific files (.project, .settings, .classpath)
4. Import > Existing Maven Projects
5. select dev-examples/input-demo and finish import
SUCCESS: Web Project works great
