  Measurements of the polarization of $\jp$ produced in pion-nucleus collisions
are in disagreement with leading twist QCD prediction where $\jp$ is observed
to have negligible polarization whereas theory predicts substantial
polarization. We argue that this discrepancy cannot be due to poorly known
structure functions nor the relative production rates of $\jp$ and $\chi_J$.
The disagreement between theory and experiment suggests important higher twist
corrections, as has earlier been surmised from the anomalous non-factorized
nuclear $A$-dependence of the $\jp$ cross section.
