I don't "think" it does. It builds with jsftemplating.jar (which
defines the HandlerContext class), but this maven dependency is marked
as "provided". The jsftemplating.jar file exists in the WEB-INF/lib
directory where it is found via the web-app classloader, but perhaps not
via the plugin-hk2-module classloader?
If it would be faster to talk over the phone, please let me know and
I'll call you. You can call me at x42083.
Thanks!!
