A DESCRIPTION OF THE PROBLEM :
There is no change in metal split pane divider's appearance to signify whether or not it is disabled. Not event the one touch expandable buttons change. This is poor design and confusing.

This problem is further exacerbated by the fact that the MetalSplitPaneDivider does not allow customization or extension since it is private to the metal package.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a split pane and change its enabled status
