The parfor loop cannot be run due to the way variable 'J' is used

I am receiving the following error in using parfor. Is there any way to use Parfor for here?
The parfor loop cannot be run due to the way variable 'J' is used
parfor xpop = 1:Xpop
Gxm = (X(xpop,M:Nvar)-0.5*ones(1,K)) * (X(xpop,M:Nvar)-0.5*ones(1,K))';
Cos = cos(X(xpop,1:M-1)*pi/2);
J(xpop,1) = prod(Cos)*(1+Gxm);
for nobj = 1:M-1
J(xpop,nobj+1) = (J(xpop,1)/prod(Cos(1,M-nobj:M-1)))...
* sin(X(xpop,M-nobj)*pi/2);
end
end*

There is, but it seems terribly unnecessary. Everything you are currently attempting to do with parfor is abundantly vectorizable,
xpop=1:Xpop;
Gxm=sum((X(xpop,M:Nvar)-.5).^2,2);
Cos = cos(X(xpop,1:M-1)*pi/2);
tmp1=prod(Cos,2).*(1+Gxm);
tmp2=tmp1./prod(Cos(1,M-nobj:M-1));
J(xpop,1:M)=[tmp1, bsxfun(@times,tmp2, sin(X(xpop,M-1:-1:1)*pi/2) )];

No, there can't be any parfor error messages. There are no for loops or parfor loops in the code I gave you.
