Benchmark crashes on Java 8 EA

[Daniel Mitterdorfer]

May I jump in? I haven't used Chris' object-pool-benchmarks project before
but I've tried it now out of keen interest and can confirm the described
behavior. Steps to reproduce on my machine:

git clone https://github.com/chrisvest/object-pool-benchmarks.git
cd object-pool-benchmarks
# I did not have org.openjdk.jol:jol-core:1.0-SNAPSHOT in my local repo and
used version 0.1 instead.
mvn clean package
java -jar target/object-pool-benchmarks.jar
".*ClaimRelease.StormpotBlaze.*" -t 8 -tu ms -bm thrpt -wi 10 -i 10 -f 1
