## How to reproduce

### The Short version
Making a call to `Selection(BetterBlockPos pos1, BetterBlockPos pos2)` makes things go boom.

I'm guessing you could make this happen by creating a vanilla mod & making a call to the function, but I don't know enough about vanilla mods to test that out.

(the longer version is below the details)
### Some more details
This seems like it's related to [this issue](https://github.com/cabaletta/baritone/issues/2865)

- The error message is identical & the stack trace is identical (up until the obfuscated code part)
- At one point, I was also having issues with `#click` crashing my game, but that no longer seems to be an issue.
- The click functionality also calls Selection(pos1, pos2) (well, it calls `BaritoneAPI.getProvider().getPrimaryBaritone().getSelectionManager().addSelection(` which calls it, but same thing)

identical portion of stack trace

```

### The long version
I'm developing a plugin for lambda & as a part of that I am making multiple selections. I tried to do this awhile ago & failed assuming it was an issue with obfuscated jars, but after updating lambda to use the unoptimized jar, and still having the issue I started digging deeper.

Anytime I make a call to create a selection using `Selection(pos1, pos2)` the process crashes. (Not the game, just the current lambda process)

To figure out what was happening I made a copy of that class, used intellij to convert it to kotlin, renamed it & ran it again with the copy to make sure I was still having the issue (I was) & then I then started picking it apart (commenting out code, restructuring things, etc). I eventually narrowed down the crash to the following:
Kotlin:
`private val min = BetterBlockPos(kotlin.math.min(pos1.x, pos2.x), kotlin.math.min(pos1.y, pos2.y), kotlin.math.min(pos1.z, pos2.z))`
Java:
`this.min = new BetterBlockPos(Math.min(pos1.x, pos2.x), Math.min(pos1.y, pos2.y), Math.min(pos1.z, pos2.z));`
Then I moved that statement from the initializer to the getter function & I was finally able to get the error included above.

Here's the final Kotlin class to go with the error log above:

BaritoneSelection.kt

```kotlin
package com.lambda.flute

import baritone.api.selection.ISelection
import baritone.api.utils.BetterBlockPos
import net.minecraft.util.EnumFacing
import net.minecraft.util.math.AxisAlignedBB
import net.minecraft.util.math.Vec3i

class BaritoneSelection(private val pos1: BetterBlockPos, private val pos2: BetterBlockPos) : ISelection {

override fun pos1(): BetterBlockPos {
return pos1
}

override fun pos2(): BetterBlockPos {
return pos2
}

override fun min(): BetterBlockPos { //crash happened on the next line
return BetterBlockPos(kotlin.math.min(pos1.x, pos2.x), kotlin.math.min(pos1.y, pos2.y), kotlin.math.min(pos1.z, pos2.z))
}

override fun max(): BetterBlockPos {
return BetterBlockPos(kotlin.math.max(pos1.x, pos2.x), kotlin.math.max(pos1.y, pos2.y), kotlin.math.max(pos1.z, pos2.z))
}

override fun size(): Vec3i {
val min = min()
val max = max()
return Vec3i(max.x - min.x + 1, max.y - min.y + 1, max.z - min.z + 1)
}

override fun aabb(): AxisAlignedBB {
val min = min()
val max = max()
return AxisAlignedBB(min, max.add(1, 1, 1))
}

override fun hashCode(): Int {
return pos1.hashCode() xor pos2.hashCode()
}

override fun toString(): String {
return String.format("Selection{pos1=%s,pos2=%s}", pos1, pos2)
}

private fun isPos2(facing: EnumFacing): Boolean {
val negative = facing.axisDirection.offset < 0
return when (facing.axis) {
EnumFacing.Axis.X -> (pos2.x > pos1.x) xor negative
EnumFacing.Axis.Y -> (pos2.y > pos1.y) xor negative
EnumFacing.Axis.Z -> (pos2.z > pos1.z) xor negative
else -> throw IllegalStateException("Bad EnumFacing.Axis")
}
}

override fun expand(direction: EnumFacing, blocks: Int): ISelection {
return if (isPos2(direction)) BaritoneSelection(pos1, pos2.offset(direction, blocks)) else BaritoneSelection(pos1.offset(direction, blocks), pos2)
}

override fun contract(direction: EnumFacing, blocks: Int): ISelection {
return if (isPos2(direction)) BaritoneSelection(pos1.offset(direction, blocks), pos2) else BaritoneSelection(pos1, pos2.offset(direction, blocks))
}

override fun shift(direction: EnumFacing, blocks: Int): ISelection {
return BaritoneSelection(pos1.offset(direction, blocks), pos2.offset(direction, blocks))
}

override fun equals(other: Any?): Boolean {
if (this === other) return true
if (javaClass != other?.javaClass) return false

other as BaritoneSelection

if (pos1 != other.pos1) return false
if (pos2 != other.pos2) return false
if (min() != other.min()) return false
if (max() != other.max()) return false
if (size() != other.size()) return false
if (aabb() != other.aabb()) return false

return true
}
}
```

## Modified settings
None

## Final checklist
- [x] I know how to properly use check boxes
- [x] I have included the version of Minecraft I'm running, baritone's version and forge mods (if used).
- [x] I have included logs, exceptions and / or steps to reproduce the issue.
- [x] I have not used any OwO's or UwU's in this issue.
