Update to post above

I believe the cli process fails from this point with this error:  
2023-07-11 17:47:51 [main] ERROR n.b.api.monitor.segment.Segments - Segments failed

Hello Kwabena,

The logging indicates that an incorrect version of Java may be installed. CCLI only supports Java 8. I recommend checking the version of Java installed on the machine and if needed, downloading and installing Java 8:

Kind regards,

I’m trying to validate a sample xpt file but I keep getting this error:

Exception in thread “main” java.lang.NoSuchMethodError: sun.nio.ch.DirectBuffer.cleaner()Lsun/misc/Cleaner;

What could I be doing wrong?  
Here’s the command I am executing:

java -jar p21-client-1.0.7.jar --engine.version=“FDA 2204.1” --standard=send --standard.version=3.1 --source.send=“C:\Users\User\Documents\practice\bw.xpt” --cdisc.ct.send.version=2023-03-31 --report=“C:\Users\User\Documents\report.xlsx” --config=“C:\Users\User\Documents\Pinnacle 21 Community\configs”
