--------------------------------------

Here is a description of this issue http://dev.eclipse.org/newslists/news.eclipse.tools.jdt/msg20024.html .
It is easier to reproduce it on slower machines, but you can reproduce it while debugging the New Seam Project wizard.
The problem also occurs within WTP classcontainers that use JavaProject.getPackageFragmentRoots() (EAR container, Web container), within the ClasspathDependencyValidator class...

I have created a patched jdt.ui plugin that fixes the issue within the Package Explorer.
The size of the new plugin is 9193KB and is placed in https://svn.jboss.org/repos/jbosstools/workspace/snjeza/jdt.ui.patch/patch2/org.eclipse.jdt.ui_3.4.1.r341_v20080827-1100.jar

Aliaksey, Anton,
Could you please add the new patched plugin and try to reproduce this issue?

Within a seam plugin, the fix is adding the following code after creating a WAR project (or after SeamProjectCreator.execute()) :

IJavaProject javaProject = JavaCore.create(project);
if (javaProject != null) {
	Object object = ((JavaProject) javaProject).getElementInfo();
	if (object instanceof JavaElementInfo && javaProject instanceof JavaProject) {
		// copied from JavaProject.buildStructure(...)
		JavaElementInfo info = (JavaElementInfo) object;
		IClasspathEntry[] resolvedClasspath = ((JavaProject) javaProject).getResolvedClasspath();
		info.setChildren(((JavaProject) javaProject).computePackageFragmentRoots(resolvedClasspath,false, null /* no reverse map */));
		((JavaProject) javaProject).getPerProjectInfo().rememberExternalLibTimestamps();
	}
}

Max,
I think that this fix is reliable. Can I commit it to CR2?
