Java and LO 7.0.beta2+ / master

Hi,

I have a problem with Java in my builds of LO7 and master.
My environment: Ubuntu 18.04.4 x86-64 with Gnome.
Java : OpenJDK 8 and 11 provided by Ubuntu
Default java : java 11

I build LO 6.4, 7.0 and master
LO 6.4 I is build with option
--with-jdk-home=/usr/lib/jvm/java-8-openjdk-amd64/

LO7 and master are build with option
--with-jdk-home=/usr/lib/jvm/java-11-openjdk-amd64

I did tests with form wizard in Base:
LO6.4 is able to use both java 8 and java 11.
LO7.0 beta2+ and master can find only java 8 and say it is defective.
If I try to add java 11 (/usr/lib/jvm/java-11-openjdk-amd64
) it say that there is no Java runtime environment in the folder I selected.

Is there something I missed in the configuration of my builds or is 
there a bug ?

Best regards.
JBF
