[Java][CI] Fix or suppress spurious errorprone warnings

[danepitkin]

Describe the enhancement requested

Search for errorprone warnings in this log file for an example: https://github.com/apache/arrow/actions/runs/7279758208/job/19836729983?pr=39329

Auto-generated code such as Arrow format can be suppressed. For hand-written code, let's try to fix them.

@danepitkin I took a look at this and seems like there are plenty of cases we need to improve. I will work on this.
Thanks for noting this. I noted this a few times when looking into CIs in the last few days.

@lidavidm I am working on fixing the warnings, and there is a warning for an unused variable context, https://github.com/apache/arrow/blob/main/java/flight/flight-core/src/test/java/org/apache/arrow/flight/TestDoExchange.java#L479-L628

Should we ignore this warning for now? I assume there should be a solid reason for introducing context to those functions.

[lidavidm]

You can remove the parameter.

[vibhatha]

Edited: (please ignore)

Also @lidavidm @danepitkin should we make a single PR for all modules or a PR per module? Any preference?

[vibhatha]

I am observing these very regularly, are these expected or maybe I have not configured things properly for Flight?
Though it doen't fail the build.
