• org.eclipse.jdt.text.tests/src/org/eclipse/jdt/text/tests/DocumentDirtyTrackerTest.java

Changed from:

 * Copyright (c) 2025 IBM Corporation and others.
 * Contributors:
 *     IBM Corporation - initial API and implementation

To:

 * Copyright (c) 2025 Carsten Hammer and others.
 * Contributors:
 *     Carsten Hammer - initial API and implementation (with assistance from GitHub Copilot)
