ExceptionInInitializerError on version 6.4

[binarynoise]

after uptating my server to 6.4, languagetool now crashes on startup.

Downgrading to 6.3.a does not crash.
I'm using the binary provided by the arch linux package

I cannot reproduce that when starting the JAR from the LT 6.4 ZIP files we provide. It looks like a packaging issue. Do you know what the actual commend is that gets executed by languagetool?

[binarynoise]

languagetool looks like a shell script to build the java command and eventually runs

/bin/java
-cp /usr/share/languagetool:/usr/share/java/languagetool/languagetool-commandline.jar:/usr/share/java/languagetool/languagetool-server.jar:/usr/share/java/languagetool/languagetool.jar
org.languagetool.server.HTTPServer
-p 8000 --public --allow-origin * --config /home/languagetool/languagetool.conf

(wrapped for readability)

[binarynoise]

here's the source for the wrapper:
https://gitlab.archlinux.org/archlinux/packaging/packages/languagetool/-/blob/main/languagetool.sh

I'll try to build the package myself and see how that goes

[danielnaber]

Does it make a difference if you run the command from the directory that contains languagetool-commandline.jar? Or from /usr/share/languagetool?

[binarynoise]

It does not seem to make a difference from where I run the full command.

[binarynoise]

looking at the code, it looks like git.properties isn't found

[binarynoise]

the file is where it should be, so it's probably a problem with invoking the jars or it's not able to properly read the file, but it doesn't log the warning either

[binarynoise]

It's definitely some kind of packaging thing.
Downloading the release zip, extracting it and running the command as in the docs successfully starts the server.

[binarynoise]

I just found the reason.
There was a stray, empty git-premium.properties in /usr/share/languagetool, getting rid of that solves the issue.
So it wasn't a packaging issue.
I wonder why it still worked on 6.3
