6950794: Make the GC log file name parameterized

[Yasumasa Suenaga]

Hi,

I use GC log rotation with -XX:+UseGCLogFileRotation .
However, suffix of logfile is fixed ( .N : cyclic 0-(NumberOfGCLogFiles-1) ) .
So I'm not easy to find the oldest log.
(I have to check timestamp of file or GC event time.)

I hope that this RFE is merged to JDK6/7/8.

Someone is working on this RFE ?
If none, I would like to contribute a patch.
(Then, please someone become a sponsor of me :-) )


Thanks,

Yasumasa
