For some reason ATI drivers return empty string for both wglGetExtensionsStringEXT and wglGetExtensionsStringARB, so JOGL can not detect presence of multisampling capabilities, and FSAA does not work. The same code works fine on NVidia cards. Other programs (Realtech VR OpenGL extension viewer and NeHe Lesson #46) show that multisampling extensions are there and are able to use them. After detalied investigation, I found that the problem caused by call to wglGetExtensionsStringARB outside of GLEventListener methods. Moving request of WGL extension string to init(...) method of GLEventListener associated with dummyGL solves problem. Suggested solution is: create additional map [device -> extensions string] in WindowsGLContextFactory, fill it in init(...) method of GLEventListener associated with dummyGL, and in WindowsGLContext.choosePixelFormatAndCreateContext(...) use value from this map instead of calling wglGetExtensionsStringARB directly.
