I'm trying to create a Java process FlameGraph with perf-java-flames. It seems to run successfully, but I can't find the resulting svg file.

$ ./perf-java-flames 161991 -F 99 -a -g -- sleep 30
Recording events for 15 seconds (adapt by setting PERF_RECORD_SECONDS)
Warning:
PID/TID switch overriding SYSTEM
$

CentOS 7
3.10.0-327.36.3.el7.x86_64
cmake version 2.8.12.2

Up-to-date versions of perf-map-agent and the FlameGraph repo.
