Yes
When using Player#getInventory().setHelmet(ItemStack) or Player#getInventory().setItem(EquipmentSlot.HEAD, ItemStack), the player is immediately disconnected from the server with the following error:
Failed to handle packet adm@282ed343, disconnecting
java.lang.IndexOutOfBoundsException: Index 46 out of bounds for length 46

... (stack trace continues)
This issue does not occur when setting the helmet using the raw inventory index 39, for example:
player.getInventory().setItem(39, new ItemStack(Material.DIAMOND_HELMET));
But the following lines cause the player to disconnect:
player.getInventory().setHelmet(new ItemStack(Material.DIAMOND_HELMET));
player.getInventory().setItem(EquipmentSlot.HEAD, new ItemStack(Material.DIAMOND_HELMET));
It also happens when setting an item in an ItemDisplay
