Review Request: Warnings cleanup in sun.management and its subpackages

[Kurchi Hazra]

Hi,

http://cr.openjdk.java.net/~khazra/7117570/webrev.00/

    Please review this webrev that cleans warnings in sun.management and 
its subpackages. These packages are now warning-free I believe.

    Looking forward to your comments. I have used the serialver tool to 
generate all the serial version UIDs that I have added.



Thanks,

Kurchi
