I think the JDT version GWT currently uses does not officially support Java 11. However Java 11 has no notable syntax changes except the var keyword for lambda parameters. So it might work, but maybe it doesn't. Have you tried running GWT with Java 11 and using that new syntax?
Also no Java API emulation additions have been added since Java 8 (and even some Java 8 stuff is still missing). I am working on a detailed list of differences between GWT HEAD and Java 11 source whenever I find time for it. This is not really a blocker, but if we state GWT supports Java 11 we might want to have the most useful API additions available. Automated releases that are tested like the SNAPSHOT builds, but with a fixed version number would be the solution to GWTs slow (fully tested) release cycle. -- J. -- You received this message because you are subscribed to the Google Groups "GWT Contributors" group.
