With different 3D models we're getting big number of warning of the following form:

Jun 06, 2013 12:33:35 AM com.sun.prism.impl.MeshNormal collect
WARNING: Face area exceeds the minimum @ face group 296; nEmptyFaces = 1

Many lines of such messages significantly affect performance on Pi.

This information could be requested in some cases but it should not be printed by default.

It is also not clear how to disable this logger. The only way I've found is to edit jre/lib/logging.properties file which is not a reasonable solution.
