GWT 2.0.0 RC2 sample errors

[Thad]

Today I downloaded and installed GWT 2.0.0 RC2, and attempted to run
the samples using `ant devmode`. I received errors on Showcase and
Mail:

Showcase: The 3 JPG images failed with javax.imageio.IIOException. I
remedied this by using ImageMagik's convert to convert them to PNG and
back to JPG. Their sizes changed by a couple bytes, and Showcase ran.

Mail: Won't run. A java.lang.VerifyError is raised:
00:00:13.154 [ERROR] Unable to load module entry point class
com.google.gwt.sample.mail.client.Mail (see associated exception for

Try upgrading to Java 6. More info is available here:

The problem with Java 6 is that I still have to support some older Mac
servers with OS X 10.4. They only run Java 1.5 or 1.4.2.

This was only an issue on Windows for me, so I haven't had to upgrade to Java 6 on my Mac in order to run the Mail sample. Are you seeing it on Mac's with Java < 6 installed?

I'm seeing the problem on my Linux box running 1.5.0_17. So long as
the gold standard here is running on Macs, I don't want to develop in
1.6 for fear of something that won't target 1.5 properly (I've been
bitten on this before).

While we are in the process of determining what exactly within the Mail sample isn't playing nicely with Java 5, is your application throwing the same error? If so, would you mind adding a code snippet to the issue that was linked within this thread?

Thanks,

Chris

I got this error as soon as I tried to use the UiBinder on Java 5,
WinXP. When I switched to Java 6, it all worked (or if I removed the
UiBinder).

A little more information: I am able to compile using Java 5 (with
the UiBinder code) and run it on Tomcat running on Java 6 (Tomcat
running on Java 5 throws the error).
