I've attached a simple maven project that will reproduce it here (m1spellcheck.zip), but this is the main class:

import java.io.IOException;
import java.util.Locale;

import org.languagetool.JLanguageTool;
import org.languagetool.Languages;

public class M1SpellCheck
{
    public static void main(String[] args)
    {
        // crash with germany, not with UK
        final var languageTool = new JLanguageTool(Languages.getLanguageForLocale(Locale.GERMANY));

        try
        {
            languageTool.check("Hello, World!");
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }

        System.out.println("Done");
    }
}

I've noticed that we don't get this crash when checking US or UK locales, but we do with German and Swedish. There may be others that cause the crash, I've not done an extensive search

Hey @danielnaber, I've released hunspell-java 2.0.0. It has one smaller breaking change but removes the dependency on bridj (replaced by plain JNA), upgrades to hunspell 1.7.1 and includes binaries for M1 Macs. It'd be great if you could give it a try!

This should be fixed now in master and with the latest snapshot (2022-11-26). Please re-open if there are still issues.
