Question: DEtools:-odeadvisor hangs !

I have never seen DEtools:-odeadvisor hang before. I've seen dsolve itself hang many times, but not odeadvisor. Is this a bug? Maple 2016.1 on windows.

restart;
eq:=(2*y(x)*diff(diff(y(x),x),x)-diff(y(x),x)^2)^3+32*diff(diff(y(x),x),x)*(x*diff(diff(y(x),x),x)-diff(y(x),x))^3 = 0;
DEtools:-odeadvisor(eq);

Now it hangs. Waited for more than one hr. This is an ODE from a book. Do others see the hang as well?
