In view of important implications in B decay, the 0^\ensuremath-0^\ensuremath- decay modes of J/\ensuremathψ are analyzed with broken flavor SU(3) symmetry in search of long-distance final-state interactions. If we impose one mild theoretical constraint on the electromagnetic form factors, we find that a large phase difference of final-state interactions is strongly favored between the one-photon and the gluon decay amplitudes. The measurement of e+e^\ensuremath-\ensuremath→\stackrel\ensuremath→\ensuremathγ\ensuremathπ+\ensuremathπ^\ensuremath- and e+e^\ensuremath-\ensuremath→\stackrel\ensuremath→\ensuremathγK+K^\ensuremath- off the J/\ensuremathψ peak can settle the issue without recourse to theory.
