Hi, I did FOSSA of Logstash 6.6.1 and Logstash-codec-plugin, both these software are under Apache 2.0 License. However both contains sub-components that are GPL, LGPL copyleft license. Fossa scanning reveals Logstash contains dependencies that are copyleft license: jmh-core jmh-core-benchmarks jmh-generator-annprocess jruby-complete" ruby-core" diff-lcs filesize jruby-openssl+0.9.19 minitar+0.5.4 rubyzip+1.1.7 1. What type of dependencies Logstash has on above components 2. How is Logstash offered under Apache 2.0 license, when it contains above sub components that has copyleft license - GPL, LGPL. 3. Are these dependencies ‘part of the program’ or ‘separate program’? 4. Are these dependencies shipped along with logstash binary? Are these build time or runtime dependencies? Thankyou, Sunil ---
