I run Kodi on a Linux Mint 19 Cinnamon system (Cinnamon version 3.8.9).

Just updated to Kodi v.18, was looking forward to Blu Ray menu support.  But in Kodi when I go to Settings/Player/Discs and try to set "Blu-Ray Playback Mode" to "Show Blu-Ray Menu" I receive an error "There was an error encountered loading Java, so BD-J menus will not be functional at this time."

I have installed Java 11 from ppa:linuxuprising/java, and run the command sudo apt install oracle-java11-set-default to set it as default.
When I run command :~$ java -version I get

java version "11.0.2" 2018-10-16 LTS
Java™ SE Runtime Environment 18.9 (build 11.0.2+7-LTS)
Java HotSpot™ 64-Bit Server VM 18.9 (build 11.0.2+7-LTS, mixed mode)

When I run:~$ javac -version I get

javac 11.0.2

And :~$ echo $JAVA_HOME returns

/usr/lib/jvm/java-11-oracle

I have tried adding the following to /etc/environment:

JAVA_HOME="/usr/lib/jvm/java-11-oracle"

But that did not help either.

What do I need to do so that Kodi can load Java and handle Blu Ray menus?

Any help greatly appreciated.
