Summary
-------

The JavaBeanXxxPropertyBuilders constructors were deprecated for removal in JDK-8229472 (CSR: JDK-8233704). They can now be removed by making them private.

Problem
-------

The constructors are marked as deprecated for removal. They need to be removed from the public API.

Solution
--------

Make the constructors private and remove the @Deprecated annotation.
