Description

In the process of building Arrow for Java on Windows, I ran into some roadblocks, which I will address either through documenting in the README.md or code changes.

So far, here's what I've got:

• if you set Git to leave line endings alone (as LF as opposed to changing to CR-LF) checkstyle will give a spurious complaint about a file not ending in a LF
• Made this into a new bug (ARROW-12111) Java has no "native" flatc (flatbuffers compiler) so the Maven build gets an unofficial binary artifact; but there's no version for Windows. I can provide an overview for building it and installing the Maven artifact locally.
