Forge 1.16.5 Not Working (FIXED)

Posted January 30, 20223 yr

FIX:

As suggested, I downgraded my java 8 to version 311 b11.
Now I can run forge servers!

Problem:

Whenever I run the forge jar (Be it through double click, open with java, cmd, or a start.bat file) I get the same error. I am using java 1.8.0_321 build 07, my java server build hotspot is build 25.321-b07 mixed mode, and forge 1.16.5-36.2.20.

I am using a 64 bit operating system if it matters.

Here's the log:

I've been searching around on forum posts, asking friends, testing things, and nothing works. Some things I've tried:

Switching java version.
Adding forge recommended java 16 args despite not running java 16.
My friends suggestion of running a totally random sequence of forge and minecraft jars.
Running everything through cmd.
Running everything through a start.bat file.

Please help. I no about nothing about java and this sun.security thing. I just want to play valhelsia 3 with my friends.

You can reply to the thread, or message me on discord (ViaticShadow#3453) and I'll update the post accordingly to aid anyone else who encounters this problem.

Thanks in advance.

New Forum Design/Update: Issues and Suggestions

Hiho,

first of all I want to say that the new forum design looks really good.

However, there are currently two issues:

In the "Unread" section, the "Mark all as Read" feature seems to be missing - or am I just overlooking it somewhere?
Some threads don’t automatically get marked as read when you open them. So the post still shows up in "Unread," even though you’ve already viewed it.
Example Thread: https://forums.minecraftforge.net/topic/159415-cannot-find-client-log-entries/

Then I have a smaller suggestion, referring to the Text Editor:

It is possible to move out the "Inline Code"-Feature from the "More Formatting Options" and add it directly to the Text Editor Tool Bar?
Same for "Quote"-Feature inside the Create Section

These two features are used quite often (at least by me) - as far as I remember, they were also available in the old forum design.

Trying to boot MC Eternal 2 Server, works on linux not on Windows 11: Jvm args error

That fixed it! it's still being weird and not actually printing anything to CMD but the logs look fine and eventually the gui generated looking normal. Thanks for your help I've done that on linux before but windows servers have always just worked with one click for some reason for me

Make sure you are using Java 17 JDK

In the start script, replace the word "java" with the java 17 path (javaw.exe) and put it into quotation marks
