[1.19.2] Fixed submitted chat event incompatible with jarInJar

[Icosider]

I have identified an error when using the ServerChatEvent.Submitted event with JarInJar dependencies. The essence of the error is that if we cancel this event and add code from the JarInJar dependency, we will get a ClassNotFoundException error. This error was detected when using Kotlin as a JarInJar dependency. Perhaps in the current PR it is worth replacing Util#ioPool from Minecraft with your own ExecutorService.

In addition, I would like to say that using CompletableFuture without your own ExecutorService is a bad practice.

Testing version: 1.19.2

Using ForkJoinPool
Configuration gradle:

dependencies {
    jarJar("org.jetbrains:annotations:[24.0.1]")
    jarJar("org.jetbrains.kotlin:kotlin-stdlib:[1.9.0]")
    jarJar("org.jetbrains.kotlin:kotlin-stdlib-common:[1.9.0]")
    jarJar("org.jetbrains.kotlin:kotlin-stdlib-jdk7:[1.9.0]")
    jarJar("org.jetbrains.kotlin:kotlin-stdlib-jdk8:[1.9.0]")
    jarJar("org.jetbrains.kotlin:kotlin-reflect:[1.9.0]")
    jarJar("org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm:[1.7.2]")
    jarJar("org.jetbrains.kotlinx:kotlinx-coroutines-jdk8:[1.7.2]")
    jarJar("org.jetbrains.kotlinx:kotlinx-coroutines-slf4j:[1.7.2]")
    jarJar("org.jetbrains.kotlinx:kotlinx-serialization-core-jvm:[1.5.1]")
    jarJar("org.jetbrains.kotlinx:kotlinx-serialization-json-jvm:[1.5.1]")
}

Mod code:

@Mod("test")
class FjkTest {
    init {
        MinecraftForge.EVENT_BUS.addListener(::onServerStarting)
    }

    private fun onServerStarting(event: ServerStartingEvent) {
        CompletableFuture.runAsync {
            testException { text ->
            }
        }
    }

    private fun testException(block: String.() -> Unit) {
        println("I will printed with exception")
    }
}

Build mod, run outside the IDE and join to world. Look at logs and check stacktrace with ClassNotFoundException: kotlin.blablabla.Lambda

Using normal ExecutorService
Configuration gradle: look at message above

Mod code:

import net.minecraft.Util

@Mod("test")
class ExecServiceTest {
    init {
        MinecraftForge.EVENT_BUS.addListener(::onServerStarting)
    }

    private fun onServerStarting(event: ServerStartingEvent) {
        CompletableFuture.runAsync({
            testException { text ->
            }
        }, Util.ioPool())
    }

    private fun testException(block: String.() -> Unit) {
        println("I will printed without exception")
    }
}
