Eclipse (GWT) doesn't run google webapplication project

I've installed Eclipse(Indigo) and Java jdk1.7.0_01. I also installed the google appengine plugin with GWT SDK 2.4.0 and App Engine SDK 1.5.5

included. The Java jdk1.7.0_01 is checked in the Eclipse preferences, installed JRE's. When I create a new google webapplication as a project in Eclipse with an example code, everything appears to be running normally and the google

webapplication is being created as a project in Eclipse. But when I try to run the project, the console comes up with the following anouncement:

Loading modules

com.demo.Demo

[ERROR] Unable to find 'com/demo/Demo.gwt.xml' on your classpath; could be a typo, or maybe you forgot to include a classpath entry for source?

[ERROR] shell failed in doStartup method

When I try to ignore this error by unchecking this error in google settings. When I run the program and when I execute the demo, I get this error message:

Colleagues on Win 7 64bit and Mac (Intel) didn't have this problem with the same code project. Are we all here Linux users? (Debian testing AMD64 for me)

I was able to fix this issue by adding -XX:-UseSplitVerifier to the JVM arguments in Project Properties -> Run/Debug Settings -> [your project's GWT config] -> Arguments -> VM Arguments. I'm not sure why it works, and that's why I'm searching the internet right now -- trying to find the "why" for my "what." :)
