A systematic analysis of the L-dependence of the J/psi-suppression in the data of the CERN NA38 and NA50 experiments shows that the anomalous suppression in the 1995 Pb-Pb data is at best a 4$\sigma$ effect at any of the L-values for the Pb-Pb data, where L is the geometrical mean path length of the J/psi in the colliding nuclei. Possible implications for the 1996 data are discussed.
