RFR: JDK-8153191: UL: Separator in VM.log output is redundant

[Yasumasa Suenaga]

Hi all,

We can check log configuration through VM.log list jcmd:
-------
Log output configuration:
#0: stdout vmoperation=debug,safepoint=info, uptime,level,tags,
#1: stderr all=warning uptime,level,tags,
#2: gc.log gc=trace, uptime,level,tags,
-------

Configuration string and decorators are ended with comma.
We should remove it as below:
-------
Log output configuration:
#0: stdout vmoperation=debug,safepoint=info uptime,level,tags
#1: stderr all=warning uptime,level,tags
#2: gc.log gc=trace uptime,level,tags
-------


I uploaded webrev for this issue.
Could you review it?

I cannot access JPRT.
So I need a sponsor.


Thanks,
