> Key: ARROW-10333

> Project: Apache Arrow

> Affects Versions: 1.0.1

> The java package (org.apache.arrow.util) is provided in two different
> artifacts
> * arrow-memory-core: ([Link to
> GitHub|https://github.com/apache/arrow/tree/master/java/memory/memory-core/src/main/java/org/apache/arrow/util])
> * arrow-vectors: ([Link to
> GitHub|https://github.com/apache/arrow/tree/master/java/vector/src/main/java/org/apache/arrow/util])
> This is causing trouble when using OSGI dependency management. After
> converting the maven artifacts to OSGI bundles the package is available via
> two chains (which is not allowed).
> Additionally, the Java 9+ module system (JPMS) does not allow for split
> packages either. See
> [here|https://www.logicbig.com/tutorials/core-java-tutorial/modules/split-packages.html].
> This was mentioned in the [mailing
> list|https://lists.apache.org/thread.html/r750c627757a7d6739651a73bd51c36fc9ade7c819eb509ed99fd03c0%40%3Cuser.arrow.apache.org%3E].
> Possible solutions are:
> * Renaming the packages to {{org.apache.arrow.vector.util}} and
> {{org.apache.arrow.memory.util}}
> * Moving the classes from vector to memory-core
