Solved
The problem is due to the file /etc/issue is empty.
Next Steps:
1> Rename the /etc/issue file, e.g: mv /etc/issue /etc/issue_backup0704
2>Re-run the test tool: java -cp . PlatformTypeTest
3>If you can run the test tool successfully without exception and get something like below, then you should be able to run PSI:
**** PT getcurrentOS: Linux
**** PT getVersion: REDHAT9
******It is not Centos8 *****
