java.nio.BufferPoolMXBean getObjectName() occasionally returns null

[Mandy Chung]

Steve,

I have prepared a patch from your contribution [1] to fix:
    7068328: BufferPoolMXBean and PlatformLoggingMXBean getObjectName 
may return null

Webrev at:
    http://cr.openjdk.java.net/~mchung/7068328/webrev.00/

I have modified the fix to move the "result = objname" assignment before 
the check to construct the ObjectName and also cover the logging 
mxbean.  Are you okay with this?

Serviceability team,
    May I get a reviewer for this patch?  I won't count myself as a 
reviewer as I modify the fix.

Thanks
Mandy
