Hello @vlsi,
I tried to run the latest release (ksar-5.2.3-all.jar) with the following version:

$ java -version
openjdk version "11.0.11" 2021-04-20
OpenJDK Runtime Environment 18.9 (build 11.0.11+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.11+9, mixed mode, sharing

And received the following error output:

$ java -jar ksar-5.2.3-all.jar

This may be related to #123. With openjdk version 1.8.0_292 it works fine.

Best regards,
