    posted a message on Minecraft vanilla Java Edition server fails to open: UnsupportedOperationException
    Quote from Carbonawk»

    So you actually use "-Xms2G -Xms4G "


    use


    -Xms2G -Xmx4G instead


    Although I do recommend a batch file, just easier long-term tbh.



    Now I realized that the command in the main post is slightly incorrect - I do use the -Xms2G -Xmx4G
    BTW, I can even dedicate 10G for the server, but it's for testing purposes only so there's no real reason why to do so

    I don't need a batch file to run it because I'm not planning to constantly shut it down and let it up, as nobody is gonna join my server - it's just to make my MOTD generator work properly

    Can you show me the text in your batch file?


    I ran the command directly from PowerShell, and it's in the main post (first line).

    What does the .\crash-reports\crash-2017-11-08_23.05.35-server.txt file looks like? Have you tried running the version 1.12.1 and see if you get the same error?





    Interesting. Seems like the problem is indeed with the version.

    I'll update the main post with the info.

    Thanks!


    EDIT: Nevermind. The problem returned.

    Hello. Whenever I try to launch a Minecraft server (using PowerShell / Command Prompt with java -Xms2G -Xmx4G .\minecraft_server.1.12.2.jar nogui), either by double-clicking the JAR or by executing it via PowerShell / Command Prompt, I keep getting the same error:

    A few extra notes:

    • I'm running Windows 10 1709 build 16299.19
    • I always keep Java updated. Java 1.8.0_151 is installed on my computer.
    • I could previously open a server. I dunno why I cannot do it now.

    Thanks for helping!

    I think you are at The wrong thread, this is The thread for minimapsync, not for voxelmap


    You're right. I posted my message here because one of the tags was [Voxelmap].

    Thanks for telling me!

    posted a message on XRay Mod (1.6.4 - 1.11) ( Vanilla/Forge/LiteLoader )

    Hello. I tried to install this mod for Forge, but the installation has failed.

    No matter if I simply put the downloaded JAR file in "mods" folder, or if I used X-Ray's installer to extract the JAR file straight into the "mods" folder - Forge ModLoader didn't recognize the files, and loaded Minecraft as if they weren't there.

    I tried to install this mod (version 4.1.5) for Forge ModLoader 11.14.3.1502.
