mkfifo testpipe
<in another shell> less -f testpipe
java -Xlog:gc:file=testpipe -jar yourjar

output of gc logs should be written to pipe
ACTUAL -
[0.002s][error ][logging] Unable to log to file /tmp/gclogpipe with log file rotation: /tmp/gclogpipe is not a regular file
[0.002s][error ][logging] Initialization of output 'file=/tmp/gclogpipe' using options '(null)' failed.
