Hi, Apache Calcite has `ubenchmark` Maven module for benchmarking purposes, and it depends on org.openjdk.jmh:jmh-core library for that. It turns out jmh-core is GPL licensed (e.g. https://mvnrepository.com/artifact/org.openjdk.jmh/jmh-core ).
Here's my question: is there a licensing issue there? Should we remove `ubenchmark` module from Calcite's sources? If so, where is the place to put it? Here's a relevant part of Calcite's pom.xml: <dependency> <groupId>org.openjdk.jmh</groupId> <artifactId>jmh-core</artifactId> <version>${jmh.version}</version> </dependency> Vladimir
