JideTabbedPane close button color

I am using JideTabbedPane and i have the close button displayed using the following:
myTabbedPane.setShowCloseButtonOnTab(true);
The problem is my tabbedpane's theme is a dark color and the "X" close button is an "X" which is black in color. The color of my tabs are set using the "ColorProvider", but i don't see anything in the documentation mentioning changing the color of the close button.
That property set in BasicJideTabbedPaneUI :
protected Color _closeButtonSelectedColor;
protected Color _closeButtonColor;
If you want change color of this button you should set new Color via UIDefaults or modify existing code in https://www.javatips.net/api/jide-oss-master/src/com/jidesoft/swing/JideTabbedPane.java

How to change POI icons in Skobbler

Is it possible to change the map POI icons with a custom image or logo? I tried from StyleEditor, but i could change only the color of the selected POI.
You can change the color and texture of that selected POI category
e.g: in the StyleEditor, select "restaurant” from the map and change its color to red->all restaurant POIs will be red.
Each POI has a unique texture ID associated to it (found in the "TexID" text box)
e.g: out-of-the box the restaurant POI has texture id 1020 associated to it
Changing the ID to another texture ID: insert the new ID (see Features window at zoom levels 17-18) in the "TexID" text box (make sure that you choose "All Levels" before making the change so that the texture changes is applied at all zoom levels).
To add a new a new texture: first, make sure the image you want to add is in PNG format, colour space RGB, and the image resolution is 512x512 px.
copy the image in StyleEditor/MapResources/Common folder or in the Style's folder (e.g: StyleEditor/DayStyle folder if you are modifying the Daystyle)
add the texture in the StyleEditor from the Dialogs menu -> “Add Textures” option
browse for the desired image, in the "Add Textures" dialog box, by pressing the + button
give it an ID (make sure its unique) by entering it in the TextureID input box
click Add & OK buttons to finish adding up the new texture
Make sure to save your style
