If you do, ensure that the JAVA_HOME variable is not pointing at the JRE. As mentioned above, the JAVA_HOME variable must point to the installation root of a JDK, which means a JDK must actually be installed.
Many of our JIRA issues are inactionable or irrelevant. We would like to request your help to ensure we can appropriately prioritize JIRA issues you’ve contributed to.
