Well, I do have a JAVAHOME=C:\ProgramData\Oracle\Java\javapath. Perhaps that is why JIRA runs at all?
I added JAVA_HOME and gave it the same path but then config complained that I must use at least Java 1.8.
I noticed that I had installed C:\Program Files (x86)\Java\jre1.8.0_131\bin\java so I changed JAVA_HOME to that but the result re: config was the same: it ran but I could still not start the JIRA service with https selected.
It surprises me that installing the JRE does not add the JAVA_HOME environment variable during installation. And what is the difference between JAVAHOME and JAVA_HOME?
Perhaps I’m getting too much into a set of JIRA/Java questions when this is a Let’s Encrypt forum. I do appreciate any help though. Still stuck.
