Re: [ovirt-devel] GWT vs. Java

From: "Vojtech Szocs" <vszocs(a)redhat.com&gt; To: devel(a)ovirt.org Cc: "Einav Cohen" <ecohen(a)redhat.com&gt;, "Roy Golan" <rgolan(a)redhat.com&gt;, "Martin Betak" <mbetak(a)redhat.com&gt; Sent: Friday, October 3, 2014 3:29:15 PM Subject: GWT vs. Java Hi guys, I've had a discussion with Roy about GWT vs. Java plans, he asked me to share this information, so here we go. GWT 2.6 ======= - patch pending merge: http://gerrit.ovirt.org/#/c/32135/ - support for Java 7 language syntax like <> operator etc. - once patch ^^ is merged, we can consolidate Java language compliance for whole Engine -> both frontend and backend can use Java 7 (yey!) GWT 2.7 ======= - planned support for *only* Java 8 language syntax like lambdas etc. but *without* emulating new Java 8 APIs like streams etc. (Java 8 API emulation should come in GWT 3.0) Likely, GWT 2.7 will remove GWT deRPC implementation on which we currently rely on. (@Martin, can you please share details?)

This means that until we move UI to REST API, we can't upgrade post GWT 2.6, so this will put more pressure to work on oVirtJS project in consequence. GWT 3.0 ======= - ETA early next year? - planned to fully support Java 8 -> both language and APIs - one of key highlights is better integration with JavaScript, which fits the scenario where GWT "application" is one module that's part of bigger application (hybrid approach) Regards, Vojtech
