Description Udo Rader

Build Identifier: 20100617-1415

Opening an XSD file with the XML Schema Desginer works only until Eclipse is restarted. 

After a restart and then trying to open the same XSD file again, a popup shows displaying "java.lang.NoClassDefFoundError: Could not initialize class org.eclipse.xsd.XSDPackage$Literals"

The .log file for such a crash shows the following stack trace:

The WST folks need to look at this.

This may be similar to bug 305973

Hmm, I am not sure, I can open WSDL files without problems.

And in fact, I can open WSDL files without problems even after I have restarted eclipse.

Hi Udo, can you please attach your schema file?

What Linux version are you using?  Can you reproduce this on Windows?
