yes it does throw the error.  I misread hthe error dialog.   Jump 
mishandles the exception and pops up a confusing dialog

           Validation Errors
              Layer: test1
              No Validation Errors

notice that both shapes report as valid.


-------------------------------------------------------------------------
 From here,  If there is no motivation for improving  the numerical 
robustness... (hope there is)

Then I really do want to be able to set arbitrary scales for the 
PrecisionManager in the geometryFactory.
difference(g1,g2,scale)
which hopefully will  keep precision levels low enough to avoid this issue.
