language_tool_python Close don't work

Hi! I'm new to this library. I did exactly this:

>>> import language_tool_python
>>> tool = language_tool_python.LanguageTool('en-US')
>>> text = 'A sentence with a error in the Hitchhiker’s Guide tot he Galaxy'
>>> matches = tool.check(text)
>>> len(matches)
2
...
>>> tool.close() # Call `close()` to shut off the server when you're done.

but the close method is stuck forever on Windows 11. I use Anaconda, Python 3.11.10.

This is my conda env:

@jegor377 Hey, did you manage to fix your problem? Normally the close bug on Windows has been fixed since the last version (2.9), that's strange. I have just retested your snippet on Windows 11, with python 3.13.1 and it works without any problems.

Hi, I figured out that if I don't use close function then program works fine and closes normally.

Mar 01 '25 07:03 jegor377

The program closes correctly but the local web server probably does not close correctly.

Mar 01 '25 15:03 mdevolde

I think that it's closing properly because when the program start, in the task manager there is some Java process that takes 2GBs of RAM and terminates as the program terminates.

Mar 03 '25 00:03 jegor377

Yes, that's just weird. I've just tried again on Windows 11 with python 3.11.11 and the close method works. I'm just wondering what makes the difference on your system.

I can also confirm that the tool.close() does not work properly. When calling it, it just hangs. I am using Python 3.11.4 with venv. Is there anything I can provide to help this bug report?

Hello, please provide as much context as possible (the contents of your venv, your operating system and its version, Python version, how you close). This will enable us to try to reproduce your bug.
