I broke the Basic Z-Wave Tool by Upgrading Hubitat and the Driver

Upgraded my C4 to 2.2.3.119

This broke the basic Z-Wave tool, so I upgraded it to the 2020-08-14 version.

All functions except Version Report work fine in the latest code.
But now a version report yields this error:

java.lang.NullPointerException: Cannot invoke method div() on null object on line 56 (parse)

The line of code claimed to be the problem is below:

54 //Z-Wave responses
55 void zwaveEvent(hubitat.zwave.commands.versionv2.VersionReport cmd) {
56 Double firmware0Version = cmd.firmware0Version + (cmd.firmware0SubVersion / 100)

The version report worked on the same device with older Hubitat microcode and the prior release of Basic Z-Wave Tool.
