> 1) -XX:+UseGCLogRotation must be used with
> -Xloggc:<filename>
> 2) -XX:NumberOfGClogFiles=<number of files> must be >=1, default is one
> 3) -XX:GCLogFileSize=<number>M (or K) default will be set to 512K
> if UseGCLogRotation set and -Xloggc gives file name, do Log rotation, depends
> on other flag settings.
> if NumberOfGClogFiles = 1, using same file, rotate log when reaches file
> capicity (set by GCLogFileSize) in <filename>.0
> if NumberOfGClogFiles > 1, rotate between files <filename>.0, <filename>.1,
> ..., <filename>.n-1
> We should add these to the commented out gc logging options in
