Replay Mod Forums

I'm really not sure what's going on here. Replay mod was working perfectly before, and then suddenly the game started crashing when initializing for some reason. All I know is if I take out Replay Mod, everything's fine. This happens with the most recent version of Replay Mod, Fabric Loader and API.

The error the launcher gives me is:
"The game crashed whilst initializing game
Error: java.lang.NullPointerException: Initializing game"

Which is helpful I'm sure.

Here's the crash log:

[Thanks for not turning that into a link forum...]

I'm having a hard time reproducing this issue.
The crash report also looks totally unrelated to the RM (it failed to fetch the list of available monitors), however other reports indicate that it does indeed have something to do with the RM (and may be OSX specific which would explain my difficulties reproducing it).

Is this you or is this another independent report of the same issue? https://github.com/FabricMC/fabric/issues/282

Another report on the forum has since been deleted without explanation, so if you find a workaround (as they might have), please don't just delete your thread but instead provide as much info about the workaround as possible. That'll help both, other people having the same issue and us in potentially narrowing it down / reproducing it.

No that's not me.

I can give you an interesting thing tho...MultiMC has the same problem, yet actually seems to ignore the error and continues loading. Replay Mod is unable to start a recording when loading into a world though. Maybe there's something useful in there.

Here are the logs for that version: https://paste.replaymod.com/jobosedipa

The error in the log of both MultiMC and non-MultiMC is totally fine and expected and shouldn't be related to the crash itself. Interesting that it doesn't crash with MultiMC though, that could mean that it's a fabric or vanilla bug which is always there but RM does something to trigger it.
Edit: It could also explain why I'm having issues reproducing the issue (I'm haven't been using the vanilla launcher in years). I'll see if I can install and reproduce it tomorrow.

The error you're getting instead seems like a separate thing. I've fixed something similar in -b2. Could you try updating to -b3 (or -b2 if you need to stay on 1.14.2) and see if that solves it?

B3 crashes with what looks like the same error. Had also updated Fabric and API.

https://paste.replaymod.com/xaqoqenoze

B3 fails to start recording on MultiMC

https://paste.replaymod.com/cibifuware

Oh, I see, MultiMC is using your system java (Java 12) by default. Try switching it to Java 8. I'll be looking into fixing Java 12 support tomorrow as well then.

Edit: Fixed with 2.2.0-b4

Recording worked!

https://paste.replaymod.com/ibihebamay

Setting vanilla launcher to system 1.8 instead of bundled still crashed it though.

Here's that log just in case: https://paste.replaymod.com/detaguzabo

So, I've tried the vanilla launcher but I'm still unable to reproduce the issue.
To narrow it down, I've decided to cut the RM in half until we either find the issue or there's nothing left.
Please try launching this version to see if it's still affected: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty.jar
Most visible functionality has already been removed in that version. So, to see if it actually loaded, you'll need to check the log (or ModMenu).

Loaded successfully! But froze on loading a world, although that's probably because of what you did to it.

https://paste.replaymod.com/lugetusisu

INTERESTING NOTE: The URI scheme error disappeared

Yes, the game failing to load the world is expected behavior (the recording part of the mod had been removed as well). Same for the lack of the URI scheme feature (or in your case error since it's not yet implemented on OSX).

Here's a new version with recording and some miscellaneous things re-enabled: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-2.jar (if it launches, you should notice buttons in the main menu having been moved to make space for the RM's buttons)

Loads fine, but crashes with "Unexpected error" (in the launcher) when loading world.

https://paste.replaymod.com/amokajohif

Yeah, contrary to what the crash says, that is actually expected. I wouldn't bother trying to load a world, the only thing we're really interested in is whether it crashes on startup.

Next one: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-3.jar (main menu should now have all buttons and Replay Viewer gui should have Upload and Edit buttons)

That crashed it.

https://paste.replaymod.com/odozobolus

Next one, main menu should look the same as with the previous one (rendering and pathing have been removed): https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-4.jar

Crashed like a bad driver...or something.

https://paste.replaymod.com/zijoyuraki

Huh? If the crash is a different one than before, please be specific. The log looks just like before (crashes this early during game startup aren't written to the log file for some reason).

If it did crash just like before, this is the next one: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-5.jar (compared to previous one, the Upload and Edit buttons in the Replay Viewer GUI should be gone and so should the Replay Center button).

?

...I thought you would ask for a crash log. I have no other information. I've just been posting latest.log like you told me to.

Here: https://paste.replaymod.com/tenuqopuru

Ah, yeah, that looks just like before. I was just confused because you suddenly mentioned something about a bad driver (which do exist and have caused issues numerous times in the past). Please continue with the jar I posted in my previous reply.

Heh I was making a joke about bad CAR drivers, as in people who don't know how to drive cars.

Sorry to scare you :)

Anyway, that jar was not a bad driver. It worked fine.

https://paste.replaymod.com/yiheloluni

Oh, car drivers, now I get it, sorry for any confusion. I was thinking of these kind of drivers: https://en.wikipedia.org/wiki/Device_driver.

Re-enabled the Replay Center part of the mod (I expect this one to crash): https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-6.jar

And it did.

https://paste.replaymod.com/mubodofano

If my suspicion is correct, this one will probably still crash but produce some extra and very valuable output in the log: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-7.jar

I'm not seeing anything new that I can find.

Here's both the crash log and latest.log:

https://paste.replaymod.com/fucugujipu

:( guess I was wrong, would have been too good, let's continue with the systematic search then: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-8.jar (to make sure logging works as I'd expect it to, I've also added two lines which should read "out test 8" and "err test 8")

That loaded fine. And I saw the test strings.

https://paste.replaymod.com/fabibapaja

I would hope this one crashes again: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-9.jar
It should also print some debug lines into the log which I'm interested in.

It crashed...and there are some new thingies.

https://paste.replaymod.com/wukojayeva

This time there are two version, please try both and post the logs for both:
https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-10a.jar
https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-10b.jar

10a worked, 10b did not.

https://paste.replaymod.com/gayotelazo

Thank you very much for all the testing!
This will be the last one for today (or yesterday actually, it's 1am here): https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-dirty-11.jar
If this doesn't crash, then I've got it narrowed down to a single line of code.
In that case, I will extract that single line out into its own separate minimal mod (might take a bit which is why I'll do it tomorrow (or today depending on how you look at it)) for you to test to make sure it's really only that line.

You're welcome! At least there's multiple reports of it so I know it's not me with an obscure system or something.

But...it crashed.

https://paste.replaymod.com/otiwonasiv

Oh, that's even more interesting, could you try adding "-Djava.awt.headless=true" to the JVM arguments in the launcher and try again?

That didn't work.

Both crash and latest.log: https://paste.replaymod.com/tuhigidoho

Oh well, I'll sleep now and will wonder about why that doesn't work later. I think I have a general idea of what needs to be fixed but it's not quite trivial to do, so I'll need quite a bit of time to do it anyway.

Alright, I've fixed what I think needed fixing. Please give this version a try: https://www.replaymod.com/replaymod-1.14.3-2.2.0-b3-2-g1b23845.jar

It worked!
