Mob spawned by spawner with potion effects gets potion swirls but not the effect itself

I created a custom zombie spawner with a custom potion effect(speed 1).
But when a zombie spawned he got the potion swirl but the effect itself(speed boost) not.

What I expected to happen was...:

The zombie getting both the speed boost and the swirl.

What actually happened was….:

The zombie only got the swirl effect.

Steps to Reproduce:
1: Create a custom zombie spawner(also tested with other mobs) and give it speed boost.
2: Let it spawn a zombie.
3: Let the zombie follow you.
4: Notice the swirls and the lack of speed boost

It seems only to happen with speed and slowness.

I think it has to do with the attribute modifiers.
When you splash a mob with a speed or slowness potion it adds an atribute modifier to the generic.movementSpeed.
This doesn't happen when you spawn a mob with a spawner.

Added the spawner that I was using

Your Java version is out of date! Please update your Java to the latest version (1.7.0_45): http://www.java.com/en/download/.

  • When using a 32-bit browser on a 64-bit operating system the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp.


Please report if the issue persists with the latest Java version.

And, as far as I know: schematics are not part of Vanilla Minecraft. Please report if you can reproduce this in Vanilla Minecraft.

Its an issue even with the latest Java version, it's been here since 1.6.x and continued into 1.7, it has critical affect on maps, for say I am making an LP of Vechs's Black Desert II and I'm forced to play on 1.4.7, its the last version where the map worked...

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.

Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been deliviered.

No response for over a year.
