GWT 2.8.0 ist raus

21.10.2016 · Christian Ullenboom

Details zu den Änderungen unter . Toll ist die Unterstützung von Java 8.

• Started using ES6 Maps when available for HashMap/HashSet that yields up 3x performance improvements.

• Partial support for Java 8 standard library APIs (see below for full list).

• Source level set to Java 8.

• Static and default methods in interfaces aren’t visible to generators. If you want to take advantage of those Java-8isms, you’re encouraged to switch to an annotation processor. This could break existing build if an interface is changed to turn a non-default method into a default method.

• Emulate java.io.UncheckedIOException.

• Emulate Optional and its int, long, double variants.

• Emulate Objects.requireNonNull() with message Supplier.

• Fix Math.min/max(float/double) emulation behavior.
