Checkstyle "Utility classes should not have a public or default constructor." error message

[Jacques Le Roux]

Hi,

Checkstyle returns 222 occurrences of the message "Utility classes should not have a 
public or default constructor."

This is due to 
https://checkstyle.sourceforge.io/config_design.html#HideUtilityClassConstructor

I don't think we need to follow the "prevents calls from subclass" suggestion  
there

I rather suggest to comment out the related class in checkstyle.xml:

ie <!-- <module name="HideUtilityClassConstructor"/> -->

If nobody is against, I'll do so in a week

Then should remain only 280 errors and hopefully most will be easy to fix. At 
least they will be easier to spot...
