Golems not attacking Mobs

Yes, my golems too rarely attack mobs. Especially noticeable if you create a golem in nether. Golems are not always attack pigzombie even if pigzombie attack me.

Is this still an issue in the current Minecraft Snapshot 15w47c or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Can confirm 16w15b. On attached screenshots pigman attack me, but golem ignore it. Golem began to attack only when I have left half of life (I've been in the diamond armor)
