Bck2Brwsr 0.50

From APIDesign

The Bck2Brwsr project has been updated to work with 2021 technologies:

• Gradle task rewritten to be compatible with 7.0
• Support for --continuous Gradle mode has been added
• Issue 19 - support for nest based access control has been implemented

No more RetroLambda. Instead of RetroLambda there is now an abstract IndyHandler interface with two implementations:

• MetafactoryHandler - generates special JavaScript for recognized Java Closures
• StringConcatHandler - converts the indy based string concatenation into simple + of JavaScript strings

The removal of RetroLambda is a good thing - the system was fragile. It relied on reflection and internal behavior of JDKs. However, replacing it with homemade implementation, is a request for regressions - finding and supporting all the corner cases, is going to take some time. Thanks to Johan Vos, who managed to compile JavaFX with Bck2Brwsr transpiler and reported quite a few bugs. The likehood Bck2Brwsr 0.50 is going to work is now higher!

The easiest way to report an error is to enhance one of existing test-cases:

• SamTest.java for JDK8 closure support
• NestMatesTest.java for JDK11 related functionality

Thanks in advance for helping Bck2Brwsr to get better!
