I have installed Java Portable (jPortable 32 bit) and I have accepted installation location:
then I have launch LibreOffice 188.8.131.52 - Multilingual-Standard, and I have enabled Java runtime:
--> Tools\Options\Advanced --> ticked 'Oracle Corporation ver. 1.8.0_361' --> Apply --> OK -> for setting up location then I have restarted, but Java RE remain unticked.
This had already happened with the latest builds.
