libreoffice unopkg failed (aarch64)

I tried to install an extension on libreoffice using unopkg command. but unokpkg failed.

xiaomi-tissot:~$ sudo unopkg add --shared H2Orestart.oxt
ERROR: Exception occurred: An error occurred while enabling: H2Orestart.jar: com.sun.star.registry.CannotRegisterImplementationException "ImplementationRegistration::registerImplementation() - The service com.sun.star.loader.Java2 cannot be instantiated at /home/buildozer/aports/community/libreoffice/src/libreoffice-7.5.5.2/stoc/source/implementationregistration/implreg.cxx:1275" at /home/buildozer/aports/community/libreoffice/src/libreoffice-7.5.5.2/desktop/source/deployment/registry/dp_backend.cxx:662

ERROR: unopkg failed.

I doubt that unopkg not working due to no libreoffice-java-common. I'm not sure. However Alpine has no libreoffice-java-common package comparing to other linux distribution. Is there any chance to include libreoffice-java-common in the near future?

Here is my testing environment. OS: 3.18.0
NAME: postmarketOS HW: Linux xiaomi-tissot 6.3.0-postmarketos-qcom-msm8953 #3 (closed)-postmarketos-qcom-msm8953 SMP PREEMPT Sat May 27 04:34:36 UTC aarch64 Linux

update: unopkg working fine on x86_64

thanks.
