JDK 9 RFR of JDK-6469562: Use compact notation to display annotation values

[joe darcy]

Hello,

Please review these changes to address

     JDK-6469562: Use compact notation to display annotation values
     http://cr.openjdk.java.net/~darcy/6469562.0/

In brief, when it is not required the noisy "value=" portion of 
annotation is now omitted in javadoc leading to a more concise display.

(The to the files used to generated the javadoc are not strictly 
necessary, but they do demonstrate that the "value=" is superfluous at a 
source level.)

Thanks,

-Joe
