I was waiting for the final release of NB 6.8 / GFv3 to test things out. In
the meantime I had placed a workaround for the Hibenate cache issue I was
suffering. Today I finally was able to launch IWebMvc2 in GFv3 final and I
have to publicly applause the work you've done. The logging issue is
magically gone and the application fully works! No issues at all. None,
zero. Kudos to all the team!!
