Sandbox 1.3.3 is an experimental Java modernization toolkit for Eclipse IDE 2026-06 (4.40) and Java 21.
Included capabilities:
• JDT cleanups and quick fixes for explicit character encodings, JFace SubMonitor migration, Eclipse Platform Status creation, general type usage and PDE XML files.
• Supported JUnit 3 and JUnit 4 to Jupiter migrations, including selected coordinated multi-file migration cases.
• Functional loop conversion, Int-to-Enum migration and method-reuse analysis.
• TriggerPattern and code-pattern authoring tools.
• Usage and API search views.
• Optional CSS formatting and validation support.
• Installed Eclipse Help for the corresponding Sandbox features.
Sandbox deliberately focuses on transformations that can be analyzed and previewed. Unsupported or ambiguous migration shapes may remain unchanged rather than being transformed speculatively.
This project is beta software. Use source control, inspect the generated preview and run the affected test suite before accepting changes in production code.
