When you use A.Resize like this (in my case, in Control Panel portlet, stock CP theme and portal settings of 6.2.x):

<aui:script use="aui-base,resize-base,liferay-store">
...
var scriptTextarea = ...;
var instance = new A.Resize({
	autoHide: false,
	node: scriptTextarea,
	wrap: true,
	handles: 'r, br, b'
});
</aui:script>

then the border handles (the arrows) are never displayed. Problem seems to be in the reference to the arrows.png file from CSS of resize-base. In FireBug console, I can see error:

"NetworkError: 400 Bad Request - http://localhost:8080/combo/arrows.png"

The CSS for resize-base uses following CSS rule:

.yui3-resize-handle-inner-r, 
.yui3-resize-handle-inner-l, 
.yui3-resize-handle-inner-t, 
.yui3-resize-handle-inner-b, 
.yui3-resize-handle-inner-tr, 
.yui3-resize-handle-inner-br, 
.yui3-resize-handle-inner-tl, 
.yui3-resize-handle-inner-bl {
    background: url("arrows.png") no-repeat scroll 0 0 transparent;
    ...
}

But the CSS is served via URL:

http://localhost:8080/combo/?browserId=firefox&minifierType=&languageId=en_US&b=6200&t=1369085618000&/html/js/aui/widget-base/assets/skins/sam/widget-base.css&/html/js/aui/resize-base/assets/skins/sam/resize-base.css
