antisymmetric jacobian for SNES?

I am looking at finite differencing a non-linear problem which has the  
square of a gradient in it.  It appears to lead to an antisymmetric  
Jacobian matrix.  Can anyone comment on whether SNES can handle an  
antisymmetric Jacobian?  If not, then could I just use snes_fd ?
