What is the smallest, simplest way to reproduce the problem?

• https://github.com/diffplug/spotless/pull/2768#discussion_r2555671425

• https://github.com/checkstyle/checkstyle/pull/18158/files#r2555889770

What did you expect to see?

// this file will be glued to the top of the specific xy-serve.js file
const debug_serve = false; // set to true for debug log output in node process
const shutdownServer = require("http-graceful-shutdown");
const express = require("express");

What did you see instead?

happens only in/after second run:

first time it was fast and fine best second time freezed everything.

endless copying the comment every run:

// this file will be glued to the top of the specific xy-serve.js file
// this file will be glued to the top of the specific xy-serve.js file
// this file will be glued to the top of the specific xy-serve.js file
// this file will be glued to the top of the specific xy-serve.js file
// this file will be glued to the top of the specific xy-serve.js file
const debug_serve = false; // set to true for debug log output in node process
const shutdownServer = require("http-graceful-shutdown");
const express = require("express");

What is the full stack trace of any errors you encountered?

Are you interested in contributing a fix to OpenRewrite?

Start by reviewing the linked Spotless and Checkstyle discussions and locating the ECMAScript6BestPractices recipe or its execution entry point. Reproduce the Maven-plugin run twice and verify that the header comment is not duplicated on subsequent runs; the issue provides no test or source file path to start from.
