In several locations we have copied code from external projects, for example flink-scala-shell/src/main/java/org/apache/flink/api/java/JarHelper.java links to the file from org.apache.xmlbeans/xmlbeans/2.4.0. We also have copied from Apache's Calcite, Spark, and Hadoop.
None of these projects are referenced in Flink's NOTICE or LICENSE. Is this unnecessary because all Apache project code is is copyright the ASF (or public domain)? Also, lodash is cited in Flink's NOTICE but there is no lodash NOTICE at https://github.com/lodash/lodash. We do properly cite the project in the MIT License section of Flink's LICENSE. Greg
