RFR: JDK-8155089: UL: Remove trailing comma from log decoration list

[Yasumasa Suenaga]

Hi all,

This review request relates [1].

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,
-------

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 a webrev for this issue.
Could you review it?

I cannot access JPRT.
So I need a sponsor.


Thanks,

Yasumasa
