Potential Code Issue - Seeking Verification

Yamakaze — Fri, 06 Feb 2026 07:32:05 GMT

I've spotted a potential code issue that appears to be a writing error, but I don't have test cases to verify what problems it might cause. Maybe I'm overthinking it, and I'd appreciate your confirmation.

version: @ArcGIS/core 4.34.8

file location：@arcgis\core\chunks\Envelope.js

class F { static getInstance() { return F.s_thisInstance } constructor() { this.m_map = new Map, this.m_vd2D = new L(1), this.m_map.set(1, this.m_vd2D), this.m_vd3D = new L(3), this.m_map.set(3, this.m_vd2D) // **This line** } GetVD2D() { return this.m_vd2D } GetVD3D() { return this.m_vd3D } FindOrAdd(t) { if (1 === t) return this.GetVD2D(); if (3 === t) return this.GetVD3D(); const e = this.m_map.get(t); if (e) return e; const s = new L(t); return this.m_map.set(t, s), s } }

On line 11:

this.m_map.set(3, this.m_vd2D)

. Based on the code from the previous two lines, I think the index 3 on line 11 should point to

this.m_vd3D

instead.
