[ttqureshi]

django.core.files.storage.handler.InvalidStorageError: Could not find backend 'require.storage.OptimizedStaticFilesStorage': No module named 'distutils'

Encountering this error because distutils has been removed in python 3.12.
Therefore making this change:
from distutils.spawn import find_executable
to
from shutil import which

Why did this need to be added? Can you add a comment?

@feanil
before making this change, I was getting the following error:

class org.mozilla.javascript.MemberBox cannot access class sun.nio.ch.FileChannelImpl 
(in module java.base) because module java.base does not export sun.nio.ch to unnamed module

The --add-exports flag allows Rhino to access Java’s internal sun.nio.ch package, which is restricted by default in Java 9+ due to the module system. Without it, Rhino fails when trying to perform file operations.

Makes sense, please add this as a comment in the file above this line so we can have it as reference if anyone asks the same question in the future.

Two small changes and then hopefully this is good to merge and release.
