Description

Using code from revision 946968, the Component Explorer demo fails to handle an exception which is thrown when 'exploring' ScrollBar in the Bounded Range Components section.

As shown below, the exception is thrown by BeanAdapter when it tries to get the 'backgroundColor' property (of org.apache.pivot.wtk.skin.terra.TerraScrollBarSkin) which happens to be a java.awt.GradientPaint rather than a java.awt.Color.

java.lang.RuntimeException: Unable to access property "backgroundColor".
