Java home:text above.
Cause
JAVA_HOME has been set to a JAVA version that is incompatible with the installed SDK version, as the SDK by default uses the JAVA installation specified by the system's JAVA_HOME environment variable.
Solution
Resolution
Upgrade the system's JAVA installation to a newer version, or point JAVA_HOME to a newer version of JAVA.
ℹ️ As of time of writing, the latest SDK Version 6.2.2 requires JAVA 1.8 or higher.
