What version of the product are you using? On what operating system?
gwtp_0.5
OS -Snow Leopard 10.6.6

Please provide any additional information below.

GoogleCodeExporter commented 8 years ago 
You have to recompile gin and gwtp with GWT 2.2 and all other GWT libs that use 
generators for that matter.

In GWT 2.2 JClassType has changed from an abstract class to an interface and 
therefor is bytecode incompatible.

Original comment by kuhnro...@gmail.com on 14 Feb 2011 at 7:31

GoogleCodeExporter commented 8 years ago 
My solution is:
 recompile latest trunk google-gin and gwtp with gwt-2.2.0

Original comment by antonev...@gmail.com on 15 Feb 2011 at 8:16

GoogleCodeExporter commented 8 years ago 
Another workaround iss to downgrade GWT SDK to 2.1

1. Download 2.1 from http://goo.gl/KKUpM
2. Set it up in Eclipse / Preferences / Tools Webkit to point to the downloaded 
location
3. Voila builds fine.

Nevertheless hoping for quick fix of this.

It will be done before the end of the day.

The latest 0.6-SNAPSHOT works with GWT 2.2 (but it doesn't work with GWT 2.1 
due to binary incompatibility). You can grab it from the CI server but I've 
also deployed a maven snapshot:
  https://oss.sonatype.org/content/repositories/snapshots/com/gwtplatform/

Info on how to use the snapshots if your project is built with Maven:

Well, Gwt-maps should be recompiled against Gwt 2.2 in the same way we did for 
Gwtp :(

Original comment by goudreau...@gmail.com on 20 Feb 2011 at 11:38

GoogleCodeExporter commented 8 years ago 
Is this really fixed? I just downloaded gwt-2.2.0 and gwt-maps-1.1.0 and this 
problem still exists.

repro:

ant gwtc

(from gwt-maps-1.1.0/samples/hellomaps)

Original comment by jim.ha...@gmail.com on 27 Feb 2011 at 5:51

GoogleCodeExporter commented 8 years ago 
Could be that gwt-maps-1.1.0 needs to be recompiled with Gwt 2.2.

Bug fixed by upgrading all depedencies to 2.2.0 version.

I install gwt yesterday (mar 2) and i still have the problem. 

Using gxt api, we have the problem :  java.lang.IncompatibleClassChangeError: 
Found interface com.google.gwt.core.ext.typeinfo.JClassType, but class was 
expected

I assume it's the same problem, and i 've not found any depedencies yet.

Original comment by gutman.dv on 3 Mar 2011 at 3:00

GoogleCodeExporter commented 8 years ago 
Most likely related to gxt not being compatible with GWT 2.2.

I just ran in to the same issue, "Caused by: 
java.lang.IncompatibleClassChangeError: Found interface 
com.google.gwt.core.ext.typeinfo.JClassType, but class was expected."
I just downloaded everything new -
1. eclipse-jee-helios-SR2-win32-x86_64
2. Java Version 1.6.0_23
3. Google Plugin for Eclipse 3.6, Ve 2.2.0.v201102111811
4. Google Web Toolkit SDK 2.2.0 2.2.0.v201102111811

I do not use GXT.

Any help would be appreciated.
Thanks

The snapshot works with GWT 2.2. If you don't want to use a snapshot, I just 
released GWTP 0.5.1 compatible with GWT 2.2. You will need GIN 1.5.

You seem to have a version of mvp4g that isnt compatible with gwt 2.2.

PURE GWT APPLICATION WORKS

gwt-servlet-2.2.0.jar

gin-1.5.9.jar
guice-3.0-rc2.jar

Does someone have gwt-maps.jar compiled for 2.2? If so, please post.

I've had the same problems as outlined above, plus a few others. I got it 
sorted in the end but after some pain. Documented how I got GWT, Eclipse, 
Maven, and Gxt/Ext working together here:

 deepakku...@gmail.com, what I did whas donwload the version 2.2.0 in my local repository with this dependency: 
<dependency>
    <groupId>com.extjs</groupId>
    <artifactId>gxt</artifactId>
    <version>2.2.0</version>
</dependency>

Then I dowloaded separately the real latest version gxt-2.2.4 . 
And I rename this version to the 2.2.0 and I replaced in my local resositorio 
(.M2/com(extjs/2.2.0). 

This worked for me with 2.3.0 version of GWT.

I hope it works for you.

Bye.

Even with GWT 2.4, the problem still persists. The google-gmaps.jar file here, 
really works. Google should fix this GWT Maps API issue.
