Excelsior JET for 64-bit Windows is now able to compile and run Java GUI applications based on Swing or SWT.
Our test suite includes, in particular, Java2Demo and SwingSet2 demos from the standard JDK samples, and SWT Paint Tool from Eclipse SWT examples.
Internally, the Garbage Collector is functionally complete but its throughput and memory footprint are yet to be optimized. Components-in-the-works are runtime support for dynamic classloading and the optimizing compiler.
Excelsior JET 8.0 Alpha 2 for Windows will be published soon.
