Description:
I installed LibreOffice 6.2.3 using the debs from libreoffice.org, and found that, at least on Kubuntu 19.04 (Disco), the application cannot find the JRE that is installed. I checked with the version that comes with Kubuntu, which is 6.2.2 and that finds the JRE automatically perfectly fine.

If I try to add the path that works for 6.2.2 manually into 6.2.3 I get a dialog that tells me that the path I've entered does not contain a JRE!

Steps to Reproduce:
1. Open LibreOffice 6.2.3
2. Open Tools -> Options -> Advanced (with use Java Runtime Environment ticked).
3. Application should detect location of existing installation of JRE.

Actual Results:
Application fails to detect existing installation of JRE, fails to populate table with path to the JRE.

Expected Results:
Application should detect existing version of JRE, since the previous version, 6.2.2 works perfectly. 


Reproducible: Always


User Profile Reset: Yes



Additional Info:
Trying to enter the path manually the application reports, with a dialog, that the path doesn't contain a JRE.
