Hello,
Can’t get latest LanguageTool-4.8.oxt extension from your main website (May 2020) installed and working onto a LibreOffice Writer v6.4.3.2 installed on a Lubuntu 20.04 machine. Getting a lot of Java (error messages see next section).

I’m not a Java power user so this is all new to me. Looking at a few Youtube videos I made a presumption that the OpenJDK is the same as using OracleJDK and that it shouldn’t be any different.
It stated on the main web page under Add-on for Libra Office that it “Requires Java 8 or later”. I installed the “default-jdk” package from the Ubuntu repositories which is LTS version 11.0.7 - but when I tried to install the extension via LibreOffice Writer it gave me many error messages. The extension does appear to be installed after restart of Libre Writer but going into Tools -> Extension Manager , I see the extension showing mostly greyed out text with message stating “Error: The status of this extension is unknown” also with a red ! showing on right side of the box. I try to enable extension and I get the same erroe message thrown at me so it’s not installong or working as expected after restart.
So I removed and restarted and attempt with installation of the “openjdk-8-jre” and got the same issue even with a “openjdk-14-jdk”. FYI, I did a “…$ sudo update-alternative --config java©” to move to alternative version of JRE/JDK but same error message as above all the time.
Thanks in advance for help.
