Test index and match some Apache projects

As reported by @ppkarwasz the following projects:
- https://github.com/apache/iceberg
- https://github.com/apache/gravitino
- https://github.com/apache/celeborn
- https://github.com/apache/hadoop (in particular the smaller JAR of https://repo1.maven.org/maven2/org/apache/hadoop/hadoop-common/3.4.1/hadoop-common-3.4.1-sources.jar )
- https://github.com/apache/amoro
- https://github.com/apache/kyuubi

... have likely all copied some code from:
- https://github.com/apache/parquet-java/

... in particular one or two of these:
- https://github.com/apache/parquet-java/blob/66e0c4eec5a7da37cc182ee0ebf6f2dbdeaac036/parquet-common/src/main/java/org/apache/parquet/util/DynConstructors.java
- https://github.com/apache/parquet-java/blob/66e0c4eec5a7da37cc182ee0ebf6f2dbdeaac036/parquet-common/src/main/java/org/apache/parquet/util/DynMethods.java

Parquet's code came first circa Summer 2017. The code is vendored, relocated, and likely refactored.

This is an interesting test for code matching.
