Hi Sergey,

Thanks for the review. Please find my comments and a new version of the 
fix inline.

There are two reasons I don't want to remove this code now:
1. This same fix needs to be back-ported to 7u8 where this code is required.
2. After changing the resizable style, native OS may or may not reset or 
somehow affect the maximum/minimum sizes of a window, and/or its real 
current size. This had best be investigated under a separate CR for JDK 8.

This makes sense even though the old code didn't do that in 
CPW.setMinimumSize(). Here's an updated webrev:
