----------------------------------------
Summary: [Java] Remove split packages in arrow-memory-core and
arrow-vectors
Key: ARROW-10333
URL: https://issues.apache.org/jira/browse/ARROW-10333
Project: Apache Arrow
Issue Type: Bug
Components: Java
Affects Versions: 1.0.1
Reporter: Benjamin Wilhelm
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
