setVisible doesn't work in Java 1.7 build 25

Sun bug # 6722346


The method setVisible should show a component that has been added but set so it is not visible.

Steps to reproduce the problem:

Click the button "Click to make a hidden button appear"

Expected result:

A button "This button was hidden" should appear

Observed result:

Using Java 1.7 build 25 the button does not appear.

Other environments tested:

This works as expected in Java 1.6.0_05 and Java 1.7 build 23.

This bug was fixed in Java 1.7 build 36.
