For the past 2 days i have been trying to get my brothers minecraft launcher to launch minecraft but **it keeps giving me the JVM error "A Java exception has occurred."**when trying to launch the game in 1.19. When typing "Java --version" into CMD I get the java version so I am guessing that this problem is from the Java Virtual Machine itself. Here is a list of things that I tried:

I have increased the memory allocation of Java in my Advanced System Settings.
I reinstalled Java twice
I reinstalled Minecraft a couple of times
I tried to change the path in Advanced System Settings
I ran Java as Admin to no avail
-I have installed both Java 8 and Java 19
Launching Minecraft in 1.12 doesn't even show me a JVM window it just tells me "Exit Code:1" in the Minecraft Launcher

I couldn't find anything on the internet and I wasn't able to find any crash logs when i tried to look for it to actually try to fix the issue. Does anyone have any solutions I can try? I know that this question isn't really about Java coding but i've asked everywhere and nobody was able to help me. Any kind of help is appreciated.
(Note: my OS is the latest version of Windows 11.)

What's the actual output of java -version?

#

Is there an environment variable called JAVA_TOOL_OPTIONS or something like that?

storm thunder Dec 23, 2022, 5:00 PM

#

normal rune What's the actual output of `java -version`?

Picked up _JAVA_OPTIONS: -Xmx1024M
java 19.0.1 2022-10-18
Java(TM) SE Runtime Environment (build 19.0.1+10-21)
Java HotSpot(TM) 64-Bit Server VM (build 19.0.1+10-21, mixed mode, sharing)

There is a System Variable called JAVA_HOME

normal rune Dec 23, 2022, 5:01 PM

#

ok that seems fine so far

#

In Minecraft, can you configure Java Executable and JVM arguments?

#

in the launcher

storm thunder Dec 23, 2022, 5:01 PM

#

Yes i can

normal rune Dec 23, 2022, 5:03 PM

#

Can you show them?

#

like the values

storm thunder Dec 23, 2022, 5:03 PM

#

For JVM Arguments i have
-Xmx4G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

#

The java exucutable just says "<Use bundled Java Runtime>"

normal rune Dec 23, 2022, 5:08 PM

#

What's the output of java -Xmx4G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -version?

storm thunder Dec 23, 2022, 5:12 PM

#

It doesnt really give me an output

#

do you mean when plugging in into cmd?

#

when plugging it into cmd it gives the same thing as before
java version "19.0.1" 2022-10-18
Java(TM) SE Runtime Environment (build 19.0.1+10-21)
Java HotSpot(TM) 64-Bit Server VM (build 19.0.1+10-21, mixed mode, sharing)

normal rune Dec 23, 2022, 5:17 PM

#

storm thunder do you mean when plugging in into cmd?

yes

#

maybe change the bundled runtime to your Java installation?

#

Is it standard Minecraft or is it modified?

storm thunder Dec 23, 2022, 5:18 PM

#

Its just standard

#

I think i already tried to do that but ill try again

#

It gives me the error:
Unable to start Java.
Error details: The requested operation requires elevation.
Filename on disk: java.exe
Path: C:\Program Files\Java\jdk-19\bin\java.exe
Exists: File

normal rune Dec 23, 2022, 5:24 PM

#

that probably means you need to run it as admin

#

elevation normally means more permissions

#

although that's kinda weird

storm thunder Dec 23, 2022, 5:24 PM

#

In properties run program as admin is ticked

#

#

cant even untick it

normal rune Dec 23, 2022, 5:29 PM

#

that shouldn't be ticked normally

storm thunder Dec 23, 2022, 5:29 PM

#

Huh

normal rune Dec 23, 2022, 5:30 PM

#

Did you enable/tick that?

storm thunder Dec 23, 2022, 5:30 PM

#

No

normal rune Dec 23, 2022, 5:30 PM

#

Does your user have permissions to access it?

dapper creekBOT Dec 23, 2022, 5:30 PM

normal rune Dec 23, 2022, 5:30 PM

#

try uninstalling your current Java version and install it from there ^

#

maybe that works

storm thunder Dec 23, 2022, 5:30 PM

#

Ok ill try

#

ok i downloaded it

#

Minecraft still won't launch

#

same error

#

Plugging in "java --version" into cmd gives me
Picked up _JAVA_OPTIONS: -Xmx1024M
openjdk 17.0.5 2022-10-18
OpenJDK Runtime Environment Temurin-17.0.5+8 (build 17.0.5+8)
OpenJDK 64-Bit Server VM Temurin-17.0.5+8 (build 17.0.5+8, mixed mode, sharing)

#

So im pretty sure it installed correctly

normal rune Dec 23, 2022, 5:43 PM

#

then select that in Minecraft

#

and if it doesn't work, edit your environment variables and remove _JAVA_OPTIONS

storm thunder Dec 23, 2022, 5:46 PM

#

normal rune then select that in Minecraft

Still didnt work

#

So just delete _JAVA_OPTIONS and keep the -Xmx part?

#

Or remove the entire variable

normal rune Dec 23, 2022, 5:50 PM

#

remove the whole variable

#

and restart

storm thunder Dec 23, 2022, 5:51 PM

#

Same error

#

Ok wait

#

When i launch the game a Command window pops up for a second then crashes and turns me back to the minecraft launcher

#

It doesnt show the regular JVM Error window where it says "A Java exception has occurred."

#

The minecraft laucnher tho still shows the same error window which is just "An Unexpected issue occurred and the game has crashed. We're Sorry for the inconvewnience. Exit Code: 1"

normal rune Dec 23, 2022, 6:04 PM

can you make a screenshot?

#

are you fast enough for that?

#

If you can get that, it might show you the actual error

storm thunder Dec 23, 2022, 6:05 PM

#

ill try to screen record

#

and then screenshot

normal rune Dec 23, 2022, 6:05 PM

#

the cmd window appears because you are using java.exe instead of javaw.exe but it just means open a cmd window and show errors there (if errors happen)

#

👍

storm thunder Dec 23, 2022, 6:07 PM

#

the command window is empty

#

#

thats the last frame it was visible

storm thunder Dec 23, 2022, 6:40 PM

#

@normal rune?

storm thunder Dec 23, 2022, 7:15 PM

#

@normal rune I was able to find the output log!

#

this was everything that was outputed when launching the game

#

I don't know what any of this means but i hope this can help!

normal rune Dec 23, 2022, 7:22 PM

#

Is Hello World your username?

#

that seems more like a problem with Minecraft itself to be honest

#

Are you using a modified version of Minecraft?

storm thunder Dec 23, 2022, 7:24 PM

#

normal rune Is `Hello World` your username?

It's the name of the user in the pc

storm thunder Dec 23, 2022, 7:24 PM

#

normal rune Are you using a modified version of Minecraft?

its unmoddified

normal rune Dec 23, 2022, 7:25 PM

#

storm thunder It's the name of the user in the pc

Can you try with a user where the name doesn't contain spaces?

#

and maybe it helps to reinstall Minecraft

#

special characters in the username can cause problems with Minecraft: https://bugs.mojang.com/browse/MCL-21856

#

Make sure there is no ! in the username

#

it might be because of the way Java interprets JAR URLs...

storm thunder Dec 23, 2022, 7:48 PM

#

Yeah I just made a new user named No and it worked perfectly

#

So it was all from the user name that i picked when i built the pc huh 😅

#

Thanks for the help big guy and sorry for taking so much time out of your day 🙏

#

You don't know how grateful I am ☺️

#

I can finally go sleep. Bye Bye!
