Wrong version check in taf-java-client

[exuvo]

Describe the bug
linux release is compiled with class file version 62 (ie java 18) but start script checks for less than 16 if [ "$ver_major" -lt "16" ]; then
My other javas were too new >20 so it chose 17 i have installed which then gives a class loader error.

OS
Linux

Version v2024.01.13
tafclient_unix_2024_01_13.tar.gz
