Question:strange odetest result. Is this valid?

Is the following valid result from odetest? is returns 0^n when 0 was expected.

Is this a bug or valid result? Maple solution is correct, so I expected 0 only not 0^n as result.

Update

Until this bug is fixed, I added the following to my code which checks for odetest result. it looks for 0^anything and changes it to 0. 

ode:=diff(y(x), x)^n= 0;
sol:=dsolve(ode);
stat:=odetest(sol,ode);
if patmatch(stat,0^a::anything) then 0; else stat; fi

gives    0

I found this problem when using odetest to check mysolution for this ode and was not getting 0 as expected,.
