First scenario (filter + servlet with same url-pattern, works):

<filter-mapping>
<filter-name>TestFilter</filter-name>
<url-pattern>/test/*</url-pattern>
</filter-mapping>

<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/test/*</url-pattern>
</servlet-mapping>

accessing /test both TestFilter and TestServlet are invoked

Second scenario (filter + servlet with different url-pattern, does not work):

<filter-mapping>
<filter-name>TestFilter</filter-name>
<url-pattern>/test</url-pattern>
</filter-mapping>

<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/test/*</url-pattern>
</servlet-mapping>

accessing /test TestFilter is invoked, TestServlet is not invoked!!!

The second scenario works fine on wildfly 8.2.0, but does not work on wildfly 9.0.2
