Announcing GPE/GWT 2.2 RC1

[Chris Ramsdale]

Today we're one step closer to shipping the Google Plugin for Eclipse and GWT SDK 2.2. The first release candidates of both of these products are ready for use, and can be installed and/or download via the links below.

Google Plugin for Eclipse 2.2 RC1 (including the GWT SDK)
Eclipse 3.6
http://dl.google.com/eclipse/plugin/beta/e36

Eclipse 3.5
http://dl.google.com/eclipse/plugin/beta/e35

Eclipse 3.4
http://dl.google.com/eclipse/plugin/beta/e34

GWT SDK 2.2 RC1 (standalone)
http://code.google.com/p/google-web-toolkit/downloads/detail?name=gwt-2.2-RC1.zip

This release includes fixes and updates for the following items:

• Fixed bad date formats in Swedish and others
• Added initial version of HTML5 Audio and Video support
• Added JRE 1.5 deprecation warning (see note below)
• Fixed bad gwt-servlet dep in samples/expenses/pom.xml, per http://code.google.com/p/google-web-toolkit/issues/detail?id=5918
• Fixed Javadoc: http://code.google.com/p/google-web-toolkit/issues/detail?q=5615
• Fixed DynaTableRf paging infinite loop
• Fixed CellBrowser hard to focus in IE
• Bumped pom.xml version, and fix NPE in samples/expenses
• Improved canvas for browsers (and permutations) with partial canvas support.
• Updated DTRF to show the use of ServiceLocators and Locators
• Fixed Showcase locales

GPE 2.2 RC1

• Fixed "Widget is disposed" errors that occur when editing Launch Configurations
• Fixed NullPointerException that occurs when deleting a launch configuration that has been launched



Version 2.2 will only have deprecated support for Java 1.5, resulting in warnings when building applications. While Java 1.5 will still work for at least the next release of GWT, developers should upgrade their version of Java to correct these warnings and ensure compatibility with future versions of GWT.

-- Chris, on behalf of the GWT, App Engine, and Google Plugin teams

What features in Java 6 would be so fundamental to GWT that 1.5 becomes deprecated ?

 

[Ümit]

Do I need a new version of gin for this release? I am asking because I get following error if I try to compile a project which works fine with GWT 2.1.1 with the new release?

java.lang.IncompatibleClassChangeError: Found interface com.google.gwt.core.ext.typeinfo.JClassType, but class was expected

at com.google.gwt.inject.rebind.GinjectorGeneratorImpl.validateInjectorClass(GinjectorGeneratorImpl.java:84)

thanks in advance

cheers

Ümit

[Christian Goudreau]

Well knowing that Java 7 is expected to be released mid 2011, I think that it's just normal to deprecated older versions. Btw, I don't understand why people keep Gwt up to date, but not Java ?

Way to go Gwt dev !

Cheers,

At some point in a project you have to move on, plus it hasn't been removed yet, just deprecated.

[Y2i]

You do.

Well, leaving aside the question of "why HAVEN'T you upgraded to Java
6", the various isEmpty () methods are quite cool, and wrth an upgrade
just for that.

[Greg Dougherty]

The other thing to remember is that if they claim to support Java 5,
then they have to test against it. Given limited testing ability,
where would you have them spend their resources:
1: Making sure Java 1.5 still works
2: Making sure Java 6 works even better?

Also it is very cool to be able to put @Override on interface methods.

I'm curious about what is keeping you on Java 5? It reached final
EOSL 16 months ago:

[Jeff Schwartz]

Java 5 is just soooo old lol. Java 6 makes me feel soooo young and Java 7 will make me feel like a kid again lol.

I bet internal infrastructure, and maybe Mac OS X (see "For developers that don't have easy access to Java 6 (such as developers using Mac OS X), the App Engine SDK is compatible with Java 5." at http://code.google.com/appengine/docs/java/gettingstarted/installing.html )

And to others, note that the @Override on interface methods and .isEmpty() on String is already supported by GWT.

[Jim Douglas]

That comment is a bit out of date. Java 6 was released for Intel Macs
running Leopard on April 29, 2008. I've been using Java 6 on this
MacBook Pro as my primary development system since October 2008.

Jim, I think when they referred to easy access they meant something like sudo apt-get install java6-sdk :-)

[Jim Douglas]

Incidentally, every GWT presentation at Google IO 2010 was done on a
Mac:

It's not so much about missing features (although it will be nice to be allowed to use and emulate features that were added to the language more than four years ago). It's more about being in step with the rest of Google's code base. Having to keep an eye out for 1.6'ism creeping in has been a non-negligible tax on the GWT team, and it's one we would like to stop paying.

I got the jars from this link: https://github.com/larsenje/google-gin-pom/tree/master/maven

They worked with GWT 2.2.0 RC1 and work now after upgrading to GWT 2.2.0

[roger7467]

Me too,what's wrong?
