David Li updated ARROW-17604:
-----------------------------
    Description: 
* Clarify where the {{--add-opens}} flag should be added (as an argument to 
{{java}})
* Demonstrate how to configure Surefire with it
* Demonstrate how to configure IntelliJ with it
* Catch the exception that results if you forget and rethrow it with a message 
telling you what to do/what docs to visit
* Investigate MemoryHandles as a possible replacement for this
* Poke MemoryUtil.UNSAFE ASAP at startup (e.g. in RootAllocator) to fail sooner
