╰$ rg 'printStackTrace()'
src/main/java/com/intuit/apl/engine/ParsingRules.java
258:          ex.printStackTrace();
266:          e.printStackTrace();

You have missed sysouts here:

samples/helloworld/src/main/java/com/sample/apl/HelloWorld.java
64:                     System.out.println(decision);
65:                     System.out.println(obligationList);
67:                     System.out.println("Error running hello world: "+e.getMessage());
78:                     System.out.println("Error warming up hello world: "+e.getMessage());
86:                     System.out.println(explanation);
88:                     System.out.println("Error explaining hello world: "+e.getMessage());
