Bug 18082 compiler pref page is the only one with icons
the icons are pretty but i think we should remove them for consistency
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/CompilerPreferencePage.java
TabItem item= new TabItem(folder, SWT.NONE);
		item.setText(JavaUIMessages.getString("CompilerPreferencePage.warnings.tabtitle")); 
		final Image errorWarningImage= JavaPluginImages.DESC_VIEW_ERRORWARNING_TAB.createImage();
		item.setImage(errorWarningImage);
		item.setControl(warningsComposite);
	
		item= new TabItem(folder, SWT.NONE);
		item.setText(JavaUIMessages.getString("CompilerPreferencePage.generation.tabtitle")); 
		final Image generationImage= JavaPluginImages.DESC_VIEW_CLASSFILEGENERATION_TAB.createImage();
		item.setImage(generationImage);
		item.setControl(codeGenComposite);
		item= new TabItem(folder, SWT.NONE);
		item.setText(JavaUIMessages.getString("CompilerPreferencePage.compliance.tabtitle")); 
		final Image jdkcomplianceImage= JavaPluginImages.DESC_VIEW_JDKCOMPLIANCE_TAB.createImage();
		item.setImage(jdkcomplianceImage);
		item.setControl(complianceComposite);
		
		validateSettings(null, null);
		folder.addDisposeListener(new DisposeListener() {
			public void widgetDisposed(DisposeEvent e) {
				errorWarningImage.dispose();
				generationImage.dispose();
				jdkcomplianceImage.dispose();
			}
		});
				
		return folder;
	}
	private Composite createWarningsTabContent(Composite folder) {
		String[] errorWarningIgnore= new String[] { ERROR, WARNING, IGNORE };
