I can´t start server.

Hello, i have got a problem with my servers. When i started the server with more than 1G it don´t worked but if i started it with lower it worked:

java -Xms2G -Xmx2G -jar forge-1.12.2-14.23.2.2632-universal.jar nogui
pause

It crashed every time and wrote to me this:

java -Xms2G -Xmx2G -jar forge-1.12.2-14.23.2.2632-universal.jar nogui
Error occurred during initialization of VM

Could not reserve enough space for 2097152KB object heap

But i have free enough RAM for this so i tried to fix it and at this page and i found some answers: https://bukkit.org/threads/complex-craftbukkit-server-and-java-problem-could-not-reserve-enough-space-for-object-heap.155192/

But it still don´t work and now it wrote to me this:                  After trying to fix it by changing "(automatically) poorly set environment variable" 

A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException
        at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)

        at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34)
        at net.minecraft.launchwrapper.Launch.main(Launch.java:28)

I will be so much happy if will someone help me with this, because I have every time started servers with only 1G and now 1G don´t works too.

Please post the output of java -version from your commandline, it will show the version of java that is being used by default/in the path.

 

It may be that you have Java 8 and 9 installed, but 9 is the one on your path.

When i did what you said it wrote this: java -version
java version "10" 2018-03-20
Java(TM) SE Runtime Environment 18.3 (build 10+46)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+46, mixed mode)

After reinstalling Java it wrote after starting server this: 

Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap

But i know that i have enough free space. So after that i checked again cmd it wrote this:

java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) Client VM (build 25.161-b12, mixed mode)

He means this : "Could not reserve enough space for 2097152KB", which is roughly 2tb.
Are you sure you are using the correct launch arguments?
Check the contents of your "run.bat" or whatever you use.

Try this instead: -Xms256m -Xmx2048m

OK, after I downloaded this new Java offline (64) because Java online downloaded to Frogram Files x86 and how did I got know there are Java versions 32-bit. I checked server, cmd and where is Java downloaded.

Now Java is in C:\Program Files\Java\jre1.8.0_161

cmd was: java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

And server after starting with:

java -Xms256m -Xmx2048m -jar forge-1.12.2-14.23.2.2632-universal.jar nogui
pause 

WORKS!!!

Thank you all so much, now i know that it was only because I am idiot and I had problem that I can fix too. :D
