Clarify Utils Class instantiation

[Jonathan-Zollinger]

Summary

because the utils class shouldn't be instantiated, any attempt to instantiate it should be met with an error.

Proposed Solution

override the default constructor with an error statement. ie

...

private Utils() {
  throw new IllegalStateException("Utility class");
}

...

Alternative

N/A

Requirements

• [] automated test validates instantiating utils class throws an error
• [] if not tested, add tests validating documented behavior
