Colin, Thomas; Since Google doesn't utilize all the code paths, I think it is important to manually test these in supported JVMs by our contributors. Any place that might have different classpath entries or places with potentially different class loaders probably good places to verify; like

Re: [gwt-contrib] Re: Java 9

I have uploaded two patches for review to allow GWT to run under a Java 9 vm. https://gwt-review.googlesource.com/#/c/19000/ https://gwt-review.googlesource.com/#/c/19001/ The main issue is (as noted by James) that the class loading has been revamped and GWT can no longer assume that the class

So, to be pedantic: Language features -> no issues there at all, since JDT happily compiles java 8 code w/ a java 9-compatible compiler. Emul updates -> standard "don't use java 9 methods if you need java 8 support" Classpathery -> Made it use ugly reflection to not require java 9 classes on

[gwt-contrib] Re: Java 9

Are there specific Java9 JRE classes that we should focus on to get into GWT? Would making GWT support Java9 sources and running in a Java9 env cause backward incompatible changes that prevent GWT from running in Java8? On Wednesday, June 7, 2017 at 2:56:46 PM UTC-5, James Nelson wrote: > > As

[gwt-contrib] Re: Java 9

As I've mentioned elsewhere, https://plus.google.com/+JamesNelsonX/posts/gBfpBDnwV9V , java 9 support is entirely possible. When I last tried it out, it required a fair number of hacks, but it worked fine. I expect the final version of java 9 modules to require slightly fewer hacks, and for
