Hi everyone, 
   
  I was trying to obtain the first five positive roots of the BesselJ[0,x], when something comes out...
   
  I type :
   
  Table[{i,FindRoot[BesselJ[0,x]==0,{x,i}]},{i,1,15,2}]//TableForm
   
  and Mathematica answer that for x=7, it obtains x->-52,6241 !
   
  Is this a bug ?
   
  Thanks for your help.
