Start with the reported stack trace in org.netbeans.modules.form.GandalfPersistenceManager.loadProperty and loadComponentProperties, then trace how FormEditor loads migrated Swing forms. Reproduce by opening the affected project on Windows 11 with JDK 17 after migration from macOS. Done means the form loads without the Unknown property exception, with the cause and a regression test or reproduction details documented.
