javac-parser is broken with Python >= 3.10

[williamjallen]

I get the following error when importing javac_parser with Python 3.10 and above:

Traceback (most recent call last):
  File ..., line 1, in </module><module>
    import javac_parser
  File "/usr/local/lib/python3.10/dist-packages/javac_parser/__init__.py", line 19, in </module><module>
    from .javac_parser import Java

    from collections import (
ImportError: cannot import name 'MutableMapping' from 'collections' (/usr/lib/python3.10/collections/__init__.py)

This appears to be coming from your usage of py4j. Can you update py4j to get this working again?
