Summary

Address reliance on default constructors for nested accessibility classes of AWT components.

Problem

The nested accessibility related classes of AWT components rely on the use of implicit Default Constructors. This is unsuitable as certain access modifiers are required for some constructors and API descriptions but are not included with the use of implicit Default Constructors. The use of explicitly defined no-arg constructors is required.

Solution

Add explicit no-args constructors to all these classes.
