-------------------------------------------------------------------

jvm_buffer should probably be kept, yes. We may also want to deprecate it (it's 
not obvious it's useful in isolation).

As for your other question: indeed, methods starting with an underscore do not 
enter into backward compatibility concerns.

> The {{pyarrow.jvm}} is currently a custom-written bridge between PyArrow and 
> Arrow Java, with limited datatype support. Now that Java implements the C 
> data interface (see ARROW-12965), we should be able to simplify the code 
> while making it more general.
> Also, we should reenable the {{conda-python-jpype}} build somewhere, for 
> example in the Crossbow nightly builds.
