  The ordering trend of magnetic impurities at low temperature results in the
frustration of the pair-breaking effect and induces a ``recovery'' of
superconducting properties. We show that this effect manifests itself in the
deviation of the Josephson current amplitude from the values obtained within
the Ambegaokar-Baratoff and the Abrikosov-Gor'kov models. We consider both weak
and strong-coupling cases. The theory is applied to describe the experimental
data obtained for the low-$T_c$ superconductor SmRh$_4$B$_4$. We further
predict a ``recovery'' effect of the Josephson current in high-temperature
superconductors.
