java: not found during Stash startup

Platform Notice: Server and Data Center Only. This article only applies to Atlassian products on the server and data center platforms.

Problem

Stash fails to start and the following appears in the catalina.out:

./catalina.sh: 1: eval: /usr/lib/jvm/java-8-oracle/jre/bin/java/bin/java: not found

The JAVA_HOME environment variable isn't problem set, so Stash is looking for bin/java in the wrong place.

Adjust JAVA_HOME for the user running Stash. In the example above it should be /usr/lib/jvm/java-8-oracle/jre instead of /usr/lib/jvm/java-8-oracle/jre/bin/java.
If the path shown in the error persists, confirm JAVA_HOME was adjusted for the correct user.
If JRE_HOME is also shown as the wrong path, confirms if there's a JRE_HOME variable set, adjusting it as well. If this isn't set, it's just going to take the value from JAVA_HOME.
