Can't get the 3rd Bessel zero!

Hi all,

I've been working with BesselJZeros recently, and the code I wrote shows
the following peculiar behavior. While I can get all the Bessel zeros I
need for most of the functions, I get mathematica to hang up at the 3rd
Bessel zero of the 0th order Bessel.

So, BesselJZeros[0,2] works, BesselJZeros[1,5] works, but
BesselJZeros[0,3] doesn't work. (waited for a couple of hours before I
aborted the calculation) Does anybody know what this behavior is due to?
Is it a bug? Has it been seen before and by anybody else? Or is it
particular to my machine?

Thanks, John
