Here lies the wrong
/usr/bin/env /opt/jdk17/bin/java .... java.ASG6Ba
Probably the file that you try to execute is ASG6Ba.java.
The provided file java.ASG6Ba with the ending ASG6Ba makes no sense for java to be executed.
Also java is a prohibited name for packages in java and since the file provided is java.ASG6Ba, java thinks that java is a package name and then follows the class name ASG6Ba. This is the specific reason the error is thrown.
Prohibited package name: java
This is also described in java documentation in chapter 6.1
The first component of a package or module name must not be the identifier java. Package and module names that start with the identifier java are reserved for packages and modules of the Java SE Platform
