Start with com.google.gdt.eclipse.suite.wizards.NewWebAppProjectWizard.java and WebAppProjectCreator.java, following the stack trace into com.google.gwt.eclipse.core.launch.LegacyGWTLaunchShortcutStrategy.java. Reproduce project creation with “Generate project sample code” disabled and inspect the failing startup-URL path. Done means the wizard creates the project successfully in that configuration without the reported NullPointerException.
