Implications of the recent discovery of the resonanceD′(1526)IJ^PC=01⁺⁺ are discussed. We consider possibilities of a mistakenJ^PC assignment forE(1420) orD′(1526). It is also pointed out that the theoretical prediction excluding low lying 1⁺⁺ glueball is based on the assumption of the valence gluon which is not necessarily true. A possibility of theE(1420) meson being 1⁺⁺ gluonium quarkonium mixture is investigated.
