Re: Janusgraph 0.5.3 potential memory leak

Can someone share how you run the benchmark (like what JMH version and what janusgraph version you are using) provided by @mad? I ran the benchmark on master (f19df6) but I see OOM errors for both iterator and iterable versions. Furthermore, I don't see any OOM report on the final result (JMH simply omits those runs with exceptions in the final report).

My environment:

# JMH version: 1.29
# VM version: JDK 1.8.0_275, OpenJDK 64-Bit Server VM, 25.275-b01
# VM invoker: /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/jre/bin/java
# VM options: -Dvisualvm.id=32547661350356 -Dfile.encoding=UTF-8 -Xmx1G

My dependencies:
