Bug 5811 [preferences] Pref to set editor background color
It would be very useful to add a preference to change the background color of the Java editor, since all of the other elements are editable.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/preferences/JavaEditorPreferencePage.java
item= new TabItem(folder, SWT.NONE);
		item.setText("&Colors");
		item.setImage(JavaPluginImages.get(JavaPluginImages.IMG_OBJS_CFILE));
		item.setControl(createColorPage(folder));
		
		item= new TabItem(folder, SWT.NONE);
		item.setText("Code A&ssist");
		item.setImage(JavaPluginImages.get(JavaPluginImages.IMG_OBJS_CFILE));
		item.setControl(createContentAssistPage(folder));
		
		initialize();
		
		return folder;
	}
	
	private void initialize() {
		
		fFontEditor.setPreferenceStore(getPreferenceStore());
		fFontEditor.setPreferencePage(this);
		fFontEditor.load();
		
		initializeFields();
		
		for (int i= 0; i < fListModel.length; i++)
			fList.add(fListModel[i][0]);
			
		fList.getDisplay().asyncExec(new Runnable() {
			public void run() {
				fList.select(0);
