RFR: JDK-8214468 : jQuery UI upgrade from 1.11.4 to 1.12.1

[Priya Lakshmi Muthuswamy]

Hi,

Kindly review the changes for jQuery UI upgrade from 1.11.4 to 1.12.1 
(https://bugs.openjdk.java.net/browse/JDK-8214468).

Modifications done:
1) As per the jQuery UI upgrade guidelines, we need to put wrappers 
around each menu item
2) Performance has degraded after updating to 1.12.4.
      Jquery UI bug : https://bugs.jqueryui.com/ticket/10050
      After applying suggestions in 
https://stackoverflow.com/questions/40782638/jquery-autocomplete-performance-going-down-with-each-search, 
its better.
3) Default theme has changed. It was smoothness theme in 1.11.4, its now 
base theme in 1.12.4.
     Using the Theme roller, used the smoothness theme and changed the 
hover color so that its similar to current Javadoc.
