Chime DTrace-GUI Tool has error for Zone CPU Usage

Chime is a java program which leverages DTrace  and presents the data
in a GUI.
I downloaded the OSOLChime-Package in Version 1.4.44

On my OpenSolaris Build 126-System. the "Zone CPU Usage" in the Categroy
"Zones" shows just an error:



Running the same version on a Solaris 10 system doesn't issue this error.
