Why the "Mean" command of the "Statistics" package gives the correct result with MAPLE 12 and MAPLE 13 and not with MAPLE 14 ?

restart;
with(Statistics):
X := RandomVariable(('Uniform')(-1, 1)):
Y := RandomVariable(('Uniform')(-1, 1)):
pdf := simplify(PDF(sqrt(X^2+Y^2), rho)):
R := RandomVariable(Distribution(PDF = unapply(pdf, rho))):


The mean may be computed using (the answer is correct)
int(rho*pdf, rho = 0 .. sqrt(2)):

          sqrt(2)/3+ln(1+sqrt(2))/6-ln(sqrt(2)-1)/6

Why the following command gives the correct result with MAPLE 12 and MAPLE 13 and not with MAPLE 14 ? Computation must be interrupted:

Mean(R):

Mean(R,numeric) is correct.
Please Wait...
