Java 8 + JS Interop
Pre-release
Pre-release
Complete Java 8 language support, tested and working in production. Java 8 still lacks some JRE emulation, but is otherwise feature complete. @JsInterface has better support, but there are still known issues around over-zealous pruning when a JsInterface returns other JsInterfaces. Current workaround is to put JavaScriptObject classes in between chained JsInterface returns.
This is rebased on Gwt master BEFORE 2.6.1 release, with pre-release features of java 8 and magic method injection. Reflection support has begun, and will be merged on the next release, after rebasing on latest GWT release.
