GlassFish detection is now part of the Environment Adapting system. Without any additional configuration on the ICEfaces' side, ICEfaces can utilize the Comet capabilities of GlassFish. However, GlassFish still needs to be configured to use Comet support.
To avoid using ARP the com.icesoft.faces.useARP property can be set to false inside the web.xml. The com.icesoft.faces.useARP property is a general property that applies to Jetty's ARP as well. The old com.icesoft.faces.useJettyContinuations can still be used but is deprecated.
Marking this one as FIXED.
This is basically a follow up to
ICE-2921.
