> We recently created the Maven module {{flink-benchmark}} for micro-benchmarks and ported most of the existing micro-benchmarks to the Java benchmarking framework JMH. However, JMH is part of OpenJDK and under GPL license which is not compatible with the AL2.
> Consequently, we need to remove this dependency and either revert the porting commits or port the benchmarks to another benchmarking framework. An alternative could be [Google's Caliper|https://github.com/google/caliper] library which is under AL2.
