will forge support java 10

[njohnson1989]

today I was testing I Minecraft will run on the newest version of java (java version 10.0.2 at the time of testing) and to my surprised Minecraft launched with no problems. it also fixed a problem with my fps that I had in single player. sadly that forge is still is encoded with Java 8. forge crashed when using Java 10 I think if forge was encoded with Java 10 it will work fine

It's not as simple as you think.
Forge uses a lot of Java backend/internal stuff and most, if not all, of it has changed between Java versions 8 and 9/10.

All of that has to be rewritten to work in Java 9+

It's being worked on though, Forge 1.13 will run on Java 9+

will it have java 8 compatibility as well? What is the difference that java 9 has changed no ASM or something, no Annotations because that's all I could think of. 

I remember reading the major changes and all that happened was new things called nodes or something?

I don't have an answer for that currently.

Worst case you can still use launcher profiles to target standalone Java installations.

Yes. The launcher ships with Java 8 currently, so it's likely that that will still be supported.

 

Mostly the classloader hacks that are done at startup. In general anything that uses reflection to hack into internals will no longer work out of the box.

I thought reflection was still in java 9+? do you have to use nodes instead to set stuff? 

Without reflection you can't even correctly set the itemstacks size without a loop. And all the methods that should be public that I invoke

Yes, of course it is. But, by default, you cannot access private methods of other modules. There are workarounds, I'll leave it to you to google.

 

What are you even talking about?

 

Dafuq?

 

Dafuq²?

for example the itemstack.stackSize cannot be directly set you cannot say itemstack.stackSize += 10; ... there are also alot of  private fields that cannot be set nor gotten related to the minecraft class.

IItemRenderer port will no longer work since it uses reflection to set an object. Many many things will break there has to be a way to allow reflection

Yes, that is how Java works. It's called encapsulation. Don't like it? Use a better language (in Kotlin you can do stack.count += 10 out of the box, because it understands Java getters and setters).

 

1. Access transformers.
2. Like I said, there are workarounds. Most likely Forge will make sure that reflection on the "minecraft module" will still work just fine.

Go away.

Ok well whatever forge uses to get private values I will just have to re-write my ReflectionUtil to match forge's even if it's an access transformer. Thanks.

@jredfox Please stop spouting your ignorant  nonsense. this is not the place for basic java tutorials.

@diesieben07 This thread is over.

 

The re-written forge will load on j8+ It has J9+ in mind but due to Minecraft currently targeting J8 it must maintain compatibility.

This is a tricky thing due to a lot of java's refactors in J9. But we are confident we can get everything working.
