Description

The  java package (org.apache.arrow.util) is provided in two different artifacts

• arrow-memory-core: (Link to GitHub)
• arrow-vectors: (Link to GitHub)
  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.

This was mentioned in the mailing list.

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
