BesselJ[2 i + 1, A Sin[t]] Sin[t], {t, 0, 2 Pi},
Assumptions -> i \[Element] Integers]

It gives 0 if A>0. Rather strange condition huh? Esp. if one
thinks about symmetry of Bessel function.

Anyway, if I put a number (e.g. 3) instead of i, v4.0 gives
other result:
(A^3*Pi*HypergeometricPFQ[{5/2}, {3, 4}, A^2/4])/64

Any clue?
