- A case study of migrating a portfolio management dashboard from Swing to JavaFX resulted in significant challenges, leading to the project's pause.
- Rewriting a legacy application involves high costs, feature parity challenges, data flow migration, testing, user retraining, and budget concerns.
- Modernizing Swing by improving user experience, updating UI, and refactoring backend code is a cost-effective approach for many companies.
- Swing still evolves through community efforts like FlatLaf, the IntelliJ Platform, and open-source Swing enhancements, indicating its ongoing relevance.
- Swing remains a valuable asset for enterprises, offering reliability and efficiency, making it a practical choice over newer tools in certain scenarios.
