Import commits from apache/arrow

[kou]

We need only commits for https://github.com/apache/arrow/tree/main/java . Other commits such as commits for .github/ aren't needed. We need to adjust other files for this repository.

We can do this by the following command lines:

git clone git@github.com:apache/arrow-java.git
cd arrow-java
git remote add arrow https://github.com/apache/arrow.git
git fetch arrow
git switch -c arrow-main-java arrow/main
git filter-branch --subdirectory-filter java
git switch main
(git log --format=%H --reverse arrow-main-java | while read commit; do git cherry-pick $commit; done)
git push origin

mvn -T 2C clean install failed because https://github.com/apache/arrow/blob/c21d85d1b3c31902c8d6f2fbf1f2a4ecfbd90772/java/vector/src/test/java/org/apache/arrow/vector/ipc/TestJSONFile.java#L321 refers https://github.com/apache/arrow/blob/main/docs/source/format/integration_json_examples/struct.json .

Let's fix it later. I'll push this as-is.
