Description

The system variable "JAVA_HOME" needs to be set as a system variable for nodetool commands to work. If this variable is not set, "decommission" will fail silently with the output:
`('The JAVA_HOME environment variable must be set to run this program!\r\nPress any key to continue . . . \r\n', '')`

However, this output is not caught or printed to the screen.
