Registrating a Java UNO Addin in an LibreOffice for which the JRE is disabled (by
disabling "Use a Java runtime environment" in Perferences->Advanced) will result in the error message
Could not create Java implementation loader
This message is unhelpful.
Fix: Improve the error message to s.th. like
"This add in requires a Java runtime. Please enable the Java runtime in ...."
- Disable Java runtime in Preferences->Advanced
- Download Obba.zip from http://www.obba.info and install Obba.oxt from "Obba for OpenOffice"
I reproduce the problem with LibreOffice 22.214.171.124.0+ and the master.
This exception is triggered here : http://opengrok.libreoffice.org/s?defs=CannotRegisterImplementationException&project=core
I agree that a more clear error message would be better.
Note: in fact the extension is installed (try a second time to install, you will get a message asking for reinstalling or canceling).
Best regards. JBF
