Bug 39244 modifiersChanged() hook not called in NewTypeWizardPage [code manipulation]
The modifiersChanged() hook in NewTypeWizardPage is not being called when a modifier radio-button is selected (public/default/private/protected), it is only being called if a check box is selected (abstract/final/static). I suspect a missing "else if" clause in typePageDialogFieldChanged() in NewTypeWizardPage is the culprit. As such am unable to extend NewTypeWizardPage and validate modifier settings (working on custom "class" wizard extension).

public void createType(IProgressMonitor monitor) throws CoreException, InterruptedException {		
		if (monitor == null) {
			monitor= new NullProgressMonitor();
		}
		monitor.beginTask(NewWizardMessages.getString("NewTypeWizardPage.operationdesc"), 10); 
		
		ICompilationUnit createdWorkingCopy= null;
		try {
			IPackageFragmentRoot root= getPackageFragmentRoot();
			IPackageFragment pack= getPackageFragment();
			if (pack == null) {
				pack= root.getPackageFragment(""); 
			}
			
			if (!pack.exists()) {
				String packName= pack.getElementName();
				pack= root.createPackageFragment(packName, true, null);
			}		
			
			monitor.worked(1);
			
			String clName= getTypeName();
			
			boolean isInnerClass= isEnclosingTypeSelected();
