I've encountered a problem when attempting to use the language-tool package for Python. This same error also occurs when using the language-check package. It seems apparent to me that the issue has got to do with the language-tool package itself, as Java itself and my LanguageTool server are both functioning.
I'm on Windows 10 running Java 10. I also tried with Java 8, which is known to work fully with LanguageTool. A different error was raised in a similar fashion with Java 8.
LanguageTool itself DOES work from the command line and the GUI also works. I successfully tested the LanguageTool server from my browser at http://localhost:8081/v2/check?language=en-US&text=my+text as well.
In addition to reinstalling the language-tool package, I've attempted to initiate my own LanguageTool Java server for Python in three ways. All three return the same error in Python. The first way is by running the following code from within a Jupyter Notebook:
import language_tool as lt
text = "This is very interesting text"
lt.correct(text, (lt.LanguageTool("en-US")).check(text))
This returns a very detailed error:

1156 finally:

The second way is by initiating a server via command-line by running java -cp languagetool-server.jar org.languagetool.server.HTTPServer --port 8081, then running the same code as about from a python terminal in the same window. This returns:
Traceback (most recent call last):

startupinfo)
OSError: [WinError 87] The parameter is incorrect
The third way I've attempted to initiate a server is by using the LanguageTool GUI and running the code about from a Notebook, which returns the same verbose output.
Finally, I tried with Java 8. In a notebook the following error was returned:

I've thoroughly consulted the documentation and have tried some other commands, all of which return the same error.
I've spent WAY too long figuring this out. Any help solving or troubleshooting would be super, super appreciated!
