May be someone who knows math better than me can look at this.

Integrate[x/(1 + (x^6*Sin[x]^2)), {x, 0, Infinity}]

Mathematica says

Integrate::idiv: Integral of x/(1+x^6 Sin[x]^2) does not converge on {0,\[Infinity]}. >>

But according to this post in the Math group

someone showed that it does converge.

Just thought to ask someone here for a second look. If you think also
this should converge, and the proof shown in the above link is
correct (it seems to be, but again, I am not a math major), I will
send a bug report to WRI
