java.util.NoSuchElementException ticking entity crash when a workstation is destroyed immediately after a villager within a 1-block radius has taken the job matching the workstation
Setup
Go into creative mode and have a workstation (tested with stonecutter and cartography table) and a villager spawn egg in your inventory. Place workstation first and then spawn villager (or vice versa) and wait for it to change its texture (meaning it has taken a job) and immediately thereafter destroy the block.
All my tests had the villager within a one-block radius of the workstation.
Expectation
The game doesn't crash, but instead causes the villager to stop working at that station as it no longer exists.
Observation
The game crashes with a ticking entity crash described as java.util.NoSuchElementException.

Changed Description:
Setting: World used for testing in all the 1.14 snapshots. After another test, appears to be any world, even a newly-created one.
First run (reproduced once): After killing a baby villager, the game crashed with a ticking entity crash. After re-joining that same world, the baby villager in question is still there. (log 2019-03-13_17.12.35-server & 2019-03-13_17.20.58-server)
Second run (reproduced once): After spawning in a villager and thereafter placing a stonecutter, the villager converts to a mason. When removing the stonecutter, the game also crashes with a ticking entity crash. (log 2019-03-13_17.23.53-server & 2019-03-13_17.27.59-server)
I have also attached the world in question.UPDATE: After doing two tests, it appears the game crashes when a villager is within at least 1 block of a 'work space'. See log 2019-03-13_17.39.25-server & 2019-03-13_17.42.37-server

Jar signature remains and both client + server brands are untouched.Setup
Go into creative mode and have a workstation (tested with stonecutter and cartography table) and a villager spawn egg in your inventory. Place workstation first. Then spawn villager (or vice versa) and wait for it to change its texture (meaning it has taken a job) and immediately thereafter destroy the block.All my tests had the villager within a one-block radius of the workstation.
Expectation
The game doesn't crash, but instead causes the villager to stop working at that station.Observation
The game crashes with a ticking entity crash described as java.util.NoSuchElementException.Crash log (attached as well crash-2019-03-28_15.32.10-server.txt

Changed Description:
Setup
Go into creative mode and have a workstation (tested with stonecutter and cartography table) and a villager spawn egg in your inventory. Place workstation first. Then spawn villager (or vice versa) and wait for it to change its texture (meaning it has taken a job) and immediately thereafter destroy the block.All my tests had the villager within a one-block radius of the workstation.
Expectation
The game doesn't crash, but instead causes the villager to stop working at that station.Observation
The game crashes with a ticking entity crash described as java.util.NoSuchElementException.Crash log (attached as well crash-2019-03-28_15.32.10-server.txt

Changed Description:
Setup
Go into creative mode and have a workstation (tested with stonecutter and cartography table) and a villager spawn egg in your inventory. Place workstation first. Then spawn villager (or vice versa) and wait for it to change its texture (meaning it has taken a job) and immediately thereafter destroy the block.All my tests had the villager within a one-block radius of the workstation.
Expectation
The game doesn't crash, but instead causes the villager to stop working at that station.Observation
The game crashes with a ticking entity crash described as java.util.NoSuchElementException.Crash log (attached as well crash-2019-03-28_15.32.10-server.txt

Changed Summary:
Villagers with a job near their workspace when it's destroyed, crash the gamejava.util.NoSuchElementException ticking entity crash when a workstation is destroyed immediately after a villager within a 1-block radius has taken the job matching the workstation
Changed Description:
Setup
Go into creative mode and have a workstation (tested with stonecutter and cartography table) and a villager spawn egg in your inventory. Place workstation first. Then spawn villager (or vice versa) and wait for it to change its texture (meaning it has taken a job) and immediately thereafter destroy the block.All my tests had the villager within a one-block radius of the workstation.
Expectation
The game doesn't crash, but instead causes the villager to stop working at that station.Observation
The game crashes with a ticking entity crash described as java.util.NoSuchElementException.Crash log (attached as well - crash-2019-03-28_15.32.10-server.txt

Go into creative mode and have a workstation (tested with stonecutter and cartography table) and a villager spawn egg in your inventory. Place workstation first and then spawn villager (or vice versa) and wait for it to change its texture (meaning it has taken a job) and immediately thereafter destroy the block.All my tests had the villager within a one-block radius of the workstation.
Expectation
The game doesn't crash, but instead causes the villager to stop working at that station as it no longer exists.Observation
The game crashes with a ticking entity crash described as java.util.NoSuchElementException.Crash log (attached as well - crash-2019-03-28_15.32.10-server.txt

Duplicate of MC-145686.
NOTE: This bug is different from MC-145686, but could be related. MC-145686 was about java.util.Optional.get(Optional.java:135), this one is about it.unimi.dsi.fastutil.longs.LongLinkedOpenHashSet.removeFirstLong (LongLinkedOpenHashSet.java:470) gotten in a near-similar environment.
Environment
Have a villager with a job near a workstation (preferably within a 1-block radius). Attached (Testing.zip) is the world I used. At -83 / -12 is a pit with a villager. This is where I performed my testing.
How to reproduce
To trigger the crash, one commonly needs to quickly destroy and place the workstation. This will cause the villager to quickly switch from being a nitwit and the job belonging to the workstation.
In the snapshots of 1.14, this crash seems to be fairly easy to reproduce, as the villager keeps its job for longer or even doesn't become a nitwit once its workstation is destroyed. In 1.14.2, villagers switch quickly between nitwit and having a job, thus it requires more destroying and placing (and more time to reproduce). Suggestion is, taken from the comments about this bug on MC-145686, to map the place and destroy buttons to keys near each other, for example E and F for placing and destroying, respectively.

Other remarks
This bug has been present since at least 19w14b, but doesn't seem to be in the game in 19w14a.
The "java.lang.IllegalStateException: POI never registered at eu
{x=1, y=56, z=9}" crash has already been reported under
MC-145756. I edited this ticket to focus on the missing optional crash.Is this still an issue in 19w13a? If it is, please provide reproduction steps.
I was unable to reproduce it so it seem to be fixed in 19w13a.
Not fixed in 19w13a. I'm assuming it wasn't fixed in 19w12a & b either, as I didn't test those versions, but based on this bug being in 19w11b, I don't think an attempt fix was done between 11b and 13a.
EDIT: Rewrote the title of this bug, as this one seems more fitting.
Can also confirm that this is still an issue in 19w13a.
Still an issue in 19w13b. Can reproduce over and over. I've been trying to grab a screen shot. This happens when the workstation is destroyed as the villager seems to focus on it.
EDIT: Here is a video of how I reproduce it (too big to upload here) : https://youtu.be/-tOcJH_LlGg
I've noticed after many crashes that there seems to be a ghost workstations left, since without any in the world a new villager takes the profession of what was previously there. Have to move several chunks away.
Another way to reproduce this is by moving the villager's composter just after the villager resets trades. https://youtu.be/fUUXfr0bXBw
Can confirm fixed for 19w14a. Villager now seems to prioritise looking at the player rather than working at a workplace and when removing its workstation using /fill, the game doesn't crash either.
Still present in 1.14.2.
Since I can't reproduce it with "fill" commands...
The fastest way to cause the bug is "using another bug". I explain it:
Flat world
Spawn a villager in a 3x3 hole.
Equip yourself on the hotbar a Workstation, for example a lectern.
Now you can simply place and break a lectern until it happens, but the fastest way is as follows:
Change "Place block" action to key "F"
Change "Destroy block" action to key "E"
Place the lectern.
Now, close to it (to avoid placing more than one block), hold E (to destroy it) and then hold F (to place it). (In this order, so the game prioritizes placing blocks faster than it breaks them).
(This should make the "place-break-place-break" action very fast, making the bug appear with a few attempts) (It's easier this way thanks to this other bug -> MC-118107 , in which "the last key that is kept pressed, repeats the action very quickly).
(I use the keyboard with this configuration because I usually play like this, and that's how I discovered that the bug persists)
I hope that the steps, though confusing in theory, will be simple to reproduce for you in practice.
I can confirm that this bug does affect 1.14.2
How I do it: In creative mode spawn in a villager and set the time of day to 2000. Nearby, place a workstation without a gui such as a lectern. Get very close and target the side closest to you, then simply press and HOLD right then left mouse buttons to break and replace repeatedly. Eventually the game will crash.

The crash you are currently experiencing is actually a tad bit different from this crash. While at first glance the crash report looks a lot like the ones of the original crash, the 1.14.2 (and, sadly, as far back as 19w14b
) crash is actually caused by something in it.unimi.dsi.fastutil.longs.LongLinkedOpenHashSet.removeFirstLong (LongLinkedOpenHashSet.java:470).
What's also different about this crash, or at least as far as I know, is that a villager can have a job (or even must (didn't test for that)) to trigger this crash.
EDIT: I've opened
MC-153355to address this specific crash. Please comment there with your findings.
