[unsolved]java.lang.ArrayIndexOutOfBoundsException


Recommended Posts

At first i was getting this while loggin into my server then i started too only get it while breaking blocks, now i just get it randomly. I've update my forge to the latest version,which allowed me to actual log int, but i getting this error on other stables version. I've also removed all mods and readded each mod one at time but still get this every so often while playing. The server also only has forge installed in the jar and in the mods UE v5.1, ICBM v5,and (myMod)Guardsman v1.3.2r1.

Get me a mod to test, and reproduceable way to test this error. This should not be happening. Unless you're using a block > 256 and you're using a build that is old.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.

Most people trying to connect to my server get this error right off the back or another related to something modification. However with almost no mods installed this error will still happen. Though for some reason i no longer crash on log in but will when running around mining, other users still crash off the back.

Get me links, I still cant reporduce this at all.

Make sure the users who are connecting that do get this error are using the latest forge.

 

This error is caused by The server using a block with ID > 256

And the client not knowing how to handle the data properly.

its a fairly straight forward error that I have fixed. And can no longer reproduce in the slightest.

So im not sure how you guys are still getting it if you are, as you say, using the latest BUILD of forge.

And I mean LATEST not the RECOMENDED

http://jenkins.minecraftforge.net:7070/job/forge/213/

Grab #213

http://calclavia.com/icbm/?page=downloads

Grab ICBM v0.5.1

http://www.minecraftforge.net/forum/index.php/topic,61.0.html

Grab UE 0.5.1

 

Put UE & ICBM in the mods folder and Forge in the .jar

By the way, this only happens on a server so DL and install those onto a quick server and join, then basically rapidly break/place blocks and jump around, I find that going into creative and flying is what usually trips it.

Similar thing:

I get an error containing "java.lang.ArrayIndexOutOfBoundsException" in the attached file (The installer log) when trying to use the windows installer for 1.8.9 forge version #1902

I'd use the most recent version of Forge 1.8.9 (Version #2318) but OptiFine doesn't support it and there's no windows installer for that version

Note: The installer doesn't create the version anyways so the error means no Forge 1.8.9

forge-1.8.9-11.15.1.1902-1.8.9-installer-win.exe.log

Not at all similar, don't post in unrelated threads.
1.8.9 is no longer supported, please update to receive support.
This thread in ancient, don't necro.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

Spoiler

Logs (Most issues require logs to diagnose):

Spoiler

Please post logs using one of the following sites (Thank you Lumber Wizard for the list):

https://gist.github.com/100MB Requires member (Free)

https://pastebin.com/: 512KB as guest, 10MB as Pro ($$$)

https://hastebin.com/: 400KB

Do NOT use sites like Mediafire, Dropbox, OneDrive, Google Drive, or a site that has a countdown before offering downloads.

 

What to provide:

...for Crashes and Runtime issues:

Minecraft 1.14.4 and newer:

Post debug.log

Older versions:

Please update...

 

...for Installer Issues:

Post your installer log, found in the same place you ran the installer

This log will be called either installer.log or named the same as the installer but with .log on the end

Note for Windows users:

Windows hides file extensions by default so the installer may appear without the .jar extension then when the .log is added the log will appear with the .jar extension

 

Where to get it:

Mojang Launcher: When using the Mojang launcher debug.log is found in .minecraft\logs.

 

Curse/Overwolf: If you are using the Curse Launcher, their configurations break Forge's log settings, fortunately there is an easier workaround than I originally thought, this works even with Curse's installation of the Minecraft launcher as long as it is not launched THROUGH Twitch:

Spoiler
  1. Make sure you have the correct version of Forge installed (some packs are heavily dependent on one specific build of Forge)
  2. Make a launcher profile targeting this version of Forge.
  3. Set the launcher profile's GameDir property to the pack's instance folder (not the instances folder, the folder that has the pack's name on it).
  4. Now launch the pack through that profile and follow the "Mojang Launcher" instructions above.

Video:

or alternately, 

 

Fallback ("No logs are generated"):

If you don't see logs generated in the usual place, provide the launcher_log.txt from .minecraft

 

Server Not Starting:

Spoiler

If your server does not start or a command window appears and immediately goes away, run the jar manually and provide the output.

 

Reporting Illegal/Inappropriate Adfocus Ads:

Spoiler

Get a screenshot of the URL bar or copy/paste the whole URL into a thread on the General Discussion board with a description of the Ad.

Lex will need the Ad ID contained in that URL to report it to Adfocus' support team.

 

Posting your mod as a GitHub Repo:

Spoiler

When you have an issue with your mod the most helpful thing you can do when asking for help is to provide your code to those helping you. The most convenient way to do this is via GitHub or another source control hub.

When setting up a GitHub Repo it might seem easy to just upload everything, however this method has the potential for mistakes that could lead to trouble later on, it is recommended to use a Git client or to get comfortable with the Git command line. The following instructions will use the Git Command Line and as such they assume you already have it installed and that you have created a repository.

 

  1. Open a command prompt (CMD, Powershell, Terminal, etc).
  2. Navigate to the folder you extracted Forge’s MDK to (the one that had all the licenses in).
  3. Run the following commands:
    1. git init
    2. git remote add origin [Your Repository's URL]
      • In the case of GitHub it should look like: https://GitHub.com/[Your Username]/[Repo Name].git
    3. git fetch
    4. git checkout --track origin/master
    5. git stage *
    6. git commit -m "[Your commit message]"
    7. git push
  4. Navigate to GitHub and you should now see most of the files.
    • note that it is intentional that some are not synced with GitHub and this is done with the (hidden) .gitignore file that Forge’s MDK has provided (hence the strictness on which folder git init is run from)
  5. Now you can share your GitHub link with those who you are asking for help.

[Workaround line, please ignore]
