The wiki has a page:

You also need to export the variable so the shell passes it to the
subprocess:

    export XAPIAN_PREFER_FLINT

Or you can just set it for a single subprocess:

    XAPIAN_PREFER_FLINT=1 ./myxapianapp

Assuming a Bourne-style shell of course...

Only quartz uses a file called "db_lock", so it isn't.

If Python creates flint databases while Java doesn't, I guess the JVM
might be clearing the environment.  That's rather annoying of it.

As a workaround, you can just create an empty flint database from Python
(or whatever) and then open it for update from Java.

You'll need to give more details...
