or  launching core_tool n VNC viewer or X-manager related tools in linux System, the message displayed as shown in the figure below

the error message appeared  that “The Java specification version of the JVM used is not 1.8.

Make sure the SAPCC_JAVA_HOME environment variable is set to the path of your SAP JVM 8 directory”


Although environment variable “SAPCC_JAVA_HOME” was already maintained  at root or <sid>adm as shown in the above figure, this could be due to either files empty or some  permission issue.
