Accumulation of pyboof_mmap_[Java process ID] in /tmp

[ancfaur]

I use pyboof in multiple python processes, to detect QR codes.

From each python process, a java process is launched and a file named "pyboof_mmap_[Java process ID]" is created in the /tmp directory. I understand this file is used for a quick communication between the python process and the java process.
However, when the java process terminates, this file is not removed and in time, many such files accumulate in the /tmp directory.

I am not sure when this file is supposed to be removed and why it's not. Could you please assist me with this issue?

What I use:
ubuntu 20.04
python3.8
openjdk 11.0.25
pyboof 0.43.1
(I tried updating to openjdk 17.0.13, but the issue persists. )
