Greg Hogan commented on FLINK-2973: ----------------------------------- [~fhueske] it looks to be GPLv2 (with classpath exception): http://hg.openjdk.java.net/jdk9/jdk9/file/a08cbfc0e4ec/LICENSE > Add flink-benchmark with compliant licenses again > ------------------------------------------------- > > Key: FLINK-2973 > URL: https://issues.apache.org/jira/browse/FLINK-2973 > Project: Flink > Issue Type: Task > Components: Build System > Affects Versions: 1.0.0 > Reporter: Fabian Hueske > Assignee: Suneel Marthi > Priority: Minor > Fix For: 1.0.0 > > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
