+underlined text+Servletcontext.getServerInfo() returns WildFly 2.2.0.Final - 1.4.0.Final instead of 10.1.0.Final. I saw WildFly 2.2.0.Final is the Wildfly Core version.
Additionally the admin interfacde shows:
Product name:  WildFly Full  
Product version:  10.1.0.Final  
Profile:  COMMUNITY  
HAL version:  2.8.27.Final  
Core version:  2.8.27.Final

Wildfly 8 is produced Wildfly 8 version sting on getServerInfo() call.
