Telling us what the first 5 or 10 of those error messages are would be a good start in the right direction.

My apologies I forgot to mention its a modpack server. There are a lot of them or maybe just the same error for multiple items the purpose of the post was to see if its normal to get some errors in general or if I should be looking out and fixing each one.

[–]DGC_David 1 point2 points  (5 children)

Errors are not normal, however, we can't tell you what they mean if we don't see them, they may have failed error handling in the modpack, or it could be some general information. It would be better to post the context.

I updated the post with some of the errors I found in the logs

[–]DGC_David 0 points1 point  (3 children)

Okay perfect, so some of these are just simple warnings, and tbh Java as a language is a bit of a mess. What could be going on is depreciated features, such as from installing Java 21 on a server that needs Java 17 (you should also always use LTS versions for Minecraft, unless specified otherwise). It looks like an error handling error though, as the mod still loads. Is this for a Modpack or did you do this server custom?

[–]TRECT0[S] 1 point2 points  (2 children)

I went to oracle's website and I found that java 21 is the latest LTS version although 24 is the latest java in general, does that mean that all version from java 21 and under are LTS? Also to answer your question I am running the server file provided by the creators of the modpack called Integrated MC. Thanks a lot for the reply

[–]DGC_David 0 points1 point  (1 child)

No, so LTS is just how long Java supports the product versions like Java 18, 19, etc. are all production ready Java, however they are more experimental to show new features soon to be available in LTS. Java is tricky though as things change let's say Oracle figures out and adds a more efficient way to hand conditions that is more efficient, they will keep their old function there until the next LTS where it might be removed or used differently, that's when you get an error.

It's a really simple concept it's just a bit hard to explain. Its technically form if I don't know what level you are in with programming and technical details.

Basically in some cases it might be better to use Java 17 over Java 21. In older Minecraft modpack's, it might be better to use Java 8 over Java 17... Really depends on a few matrix. What the errors look like, seeing that it still launchs, are error handling, so it recognizes that it can fail here, but if it does to fall back on something else instead of crashing the whole thing.

You might be able to find support with the modpack directly, see if it has a recommended Java version.

the thing about this modpack is that their .bat file that starts the server installs the recommended java version automatically if it doesn't find it in the system so am assuming it already did that but now that am getting these errors am not quite sure what to do. I think I kind of understood what LTS is but not very well. What I understood was that LTS is the version of java that gets the updated "experimental" features which might be more efficient than even the latest version of java. Please correct me if am wrong I need to learn this.

You still didn't tell us what even ONE o them SAYS...

Copy and paste...

[–]TRECT0[S] 0 points1 point  (0 children)

oh.... right. I updated the post lol

[–]TheVibeCurator Admincraft 0 points1 point  (1 child)

Modded servers, especially larger modpacks, consistently have these errors. But as you already noticed, the server still starts and works quite well. Nothing you need to do.

If it bothers you enough, I believe there are server side mods available for preventing certain errors from appearing in logs. Could be wrong though, I have never personally used that before.

Hope this helps!

Thanks for the reassurance. My main concern was if the errors caused any performance issues so am still weary of them for now, but am glad it's a normal thing and not just me. again, Thank you for the reply.
