Proposed Java change to DEBUG defaults

[Larry White <lj...@gmail.com>]

Hi all,

There's a proposed change to Java build defaults that I would like to get
into the next release if possible. The issue is well described in a GitHub
issue BaseAllocator.DEBUG should be opt-in
<https://github.com/apache/arrow/issues/34338>, so I won't go into the
details here, but the current settings cause significant performance
degradation in basically all test runs and JUnit usages in IDEs.

If you have any concerns about how this might affect your development
experience, please take a look at the GitHub issue and comment there,
and/or reply to this thread.

Thanks,

Larry
