<Swing Dev> RFR JDK-8245785: javax.swing.JTabbedPane cannot be deserialized

[Prasanta Sadhukhan]

Hi Sergey,

It seems "pages" object is not instantiated as readObject() did not read 
the object. I have modified the code to read the "pages" object after 
deserialization and now

if JTabbedPane has few tabs/pages, all are deserialized. This is also 
tested in the testcase.
