No response

Expected behaviour

Opening TeXstudio, configure "LT Path" to /usr/share/java/languagetool/languagetool-server.jar. Clicking Help -> Check LanguageTool is expected to show that LanguageTool is configured correctly:

which java: /usr/bin/java

JAVA: java
openjdk version "11.0.12" 2021-07-20

Actual behaviour

Instead:

which java: /usr/bin/java

JAVA: java
openjdk version "11.0.12" 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+7-void-r3)

LT current status: error


LT-URL: http://localhost:8081/v2/check

Executing the jar command to start LanguageTool shows:

On the other hand, running the Void packaged LanguageTool binary from the command line (languagetool --http -p 8081) does work.

Steps to reproduce

1. Start TeXstudio
2. Add path to languagetool-server.jar to configuration.
3. Check LanguageTool from TeXstudio

Start by comparing how the configured /usr/share/java/languagetool/languagetool-server.jar is launched with the working languagetool --http -p 8081 command. Reproduce the NoClassDefFoundError for org/slf4j/LoggerFactory and trace the LanguageTool package's Java invocation and dependencies. Done means TeXstudio's LanguageTool check reports the status as working.
