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.
Application fails to detect existing installation of JRE, fails to populate table with path to the JRE.
Application should detect existing version of JRE, since the previous version, 6.2.2 works perfectly.
User Profile Reset: Yes
Trying to enter the path manually the application reports, with a dialog, that the path doesn't contain a JRE.
