You'll need to change your setup so that it uses a valid supported version of Java.

I am facing same issue.

Please help me

Nic Brough -Adaptavist- · Answer

There are three lines in here I would worry about:

1. JAVA_HOME "C:\Program Files\Java\jdk-13.0.2" contains spaces.

It would be a good idead to fix the spaces things, it can give you problems later, but the thing I am really worried about is the very invalid version of Java you have there.  13.0.2 can work, but it implies you are using something you have not configured the rest of your setup to work with

2. Wrong JVM version! Jira requires 1.8 or 11 to run

That's the "smoking gun" - it's found a totally unsupported JVM to try to run with

3. Environment variable 'ignore_jvm_version' is set to 'true'

Do not do this.  Atlassian systems are no more or less intolerant than most others of unsupported JVMs - they'll try, but when it's not a valid version, they'll fail and not worry about it beyond saying "unsupported".

The very short answer to this question is "stop trying to run it with an unsupported JVM".  First thing to do is use a supported one, as defined in https://confluence.atlassian.com/adminjiraserver/supported-platforms-938846830.html
