Invalid maximum heap size

Hello,
I'm having the following error when running the run.bat that I created inside the server folder with the following command lines copied from your wiki :

java -Xmx8G -Xms8G -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=0 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -XX:+ UseG1GC -jar forge-1.16.5-36.2.8.jar nogui
pause

After executing this file, the following message appears in cmd:

E:\Above+and+Beyond-1.3-Server>java -Xmx8G -Xms8G -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=0 -XX:G1ReservePercent=20 -XX: MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -XX:+UseG1GC -jar forge-1.16.5-36.2.20.jar nogui
Invalid maximum heap size: -Xmx8G
The specified size exceeds the maximum representable size.
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

If I try to open "forge-1.16.5-36.2.20.jar" it doesn't work. Nothing happens.

I already tried reducing "-Xmx8G -Xms8G" to "-Xmx4G -Xms4G" and it gave the same error...

When I download the server files folder in curseforge it already comes with "forge-1.16.5-36.2.20-installer.jar", so, apparently, the server folder itself that is in curseforge installs forge version 1.16.5-36.2.20. Should I install forge version 1.16.5-36.2.8?

My settings:

Windows 11
JAVA 8
forge-1.16.5-36.2.20
16GB RAM

I installed java 1.8.0_311 and forge-1.16.5-36.2.26 (only in the server folder) and it seems to have worked.... I'm playing with my friend like this. I believe that if you install just forge-1.16.5-36.2.26 it might work well... You have to test it...

I tried with "-Xmx1G -Xms1G" and it seems like it was, however, it gave another error:

E:\Above+and+Beyond-1.3-Server>java -Xmx1G -Xms1G -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=0 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M -XX:+UseG1GC -jar E:\Above+and+Beyond-1.3-Server\forge-1.16.5-36.2.20.jar nogui

Can you post the output of running java -version?

I suspect you're running a 32-bit version of Java which does not support heap sizes above 4 GB. The default downloader on the Java website is 32-bit.

The other issue you ran into is probably related to #434, looks like a Java/Forge compatibility issue.

mayconvs · Answer 5 · 2023-12-12T19:47:59.000Z

@glektarssza Yes!

java version "1.8.0_311"
Java(TM) SE Runtime Environment (build 1.8.0_311-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.311-b11, mixed mode)

glektarssza · Answer 6 · 2023-12-12T19:53:28.000Z

Okay, you've got a 64-bit version of Java. That's good. I'll check my configuration once I'm off work in about 1.5 hours. I know I'm running with 8 GB of RAM allocated to Minecraft but I did need to update my version of Forge and Java. I'm using the latest of each, so latest Forge for 1.16.5 and the latest Java 8 JRE. Version numbers will be posted shortly.

glektarssza · Answer 7 · 2023-12-12T19:58:52.000Z

Alrighty. I'm using:

Java 1.8.0_392 (from Temurin)
Minecraft 1.16.5
Forge 36.2.39
LWJGL 3.2.2

JVM Arguments:

-XX:+UseG1GC -Dsun.rmi.dgc.server.gcInterval=2147483646 -XX:+UnlockExperimentalVMOptions -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M --add-opens=java.base/sun.security.util=ALL-UNNAMED --add-opens=java.base/java.util.jar=ALL-UNNAMED -XX:+IgnoreUnrecognizedVMOptions -Xmx8G -Xms8G
