Bug 17603 Name Conflict dialog should be improved
Build F1 See attached picture. The problem is that that CU name including the .java is in quotes and that the user should enter a new name for it. Unfortunately . is not accepted in that name. We should use better wording.

return "Resource exists with different case";
					
				return null;
			}
		};
		return validator;
	}
	private static IInputValidator createCompilationUnitNameValidator(final ICompilationUnit cu) {
		IInputValidator validator= new IInputValidator(){
			public String isValid(String newText) {
				if (newText == null || "".equals(newText))
					return EMPTY;
				String newCuName= newText + ".java";
				IStatus status= JavaConventions.validateCompilationUnitName(newCuName);	
				if (status.getSeverity() == IStatus.ERROR)
					return status.getMessage();
				RefactoringStatus refStatus;
				try {
					refStatus= Checks.checkCompilationUnitNewName(cu, newText);
				} catch (JavaModelException e) {
					return EMPTY;
				}
				if (refStatus.hasFatalError())
					return refStatus.getFirstMessage(RefactoringStatus.FATAL);
				if (cu.getElementName().equalsIgnoreCase(newCuName))
					return "Resource exists with different case";
