Thank you for the bug report.  I have had a look and this is actually a 
problem in the ode2() function. 

In share/diffequations/ode/ode2.mac we have:  

bessel2(a,b):=block([nu,b1,intp,radexpand:'all,%k1,%k2],
   if not(freeof(x,y,b1: ratsimp((1-b)*(x-pt)^2))) then return(false),
   if ratsimp(a*(x-pt)) # 1 then return(false),
   nu: sqrt(b1), method: 'bessel,
   if nu = 1/2 then return(y = (%k1*sin(x-pt) +
%k2*cos(x-pt))/sqrt(x-pt)),
   if featurep(nu,'integer) then intp: 'y else if numberp(nu) then intp:
'n,
 loop,
   if not(intp='y or intp='n)
     then (intp: readonly("is", nu, "an integer?  type y or n."),
go(loop)),
   if intp = 'y then return(y = %k1*bessel_j(nu,x-pt) +
%k2*bessel_y(nu,x-pt)),
   return(y = %k1*bessel_j(nu,x-pt) + %k2*bessel_j(-nu,x-pt)))$



I thought that the askinteger() function might be part of the solution.
However:

(%i1) askinteger(sqrt(3));
Is sqrt(3) an integer?
no;
(%o1)                                 no
