@ottobackwards , regarding Set vs List. Validation Result supposed to be 
Collection, so technically - any of them can be used. But consistency should 
come with Set, as if you check super class AbstractConfigurableComponent, its 
customValidate returns:
return Collections.emptySet();
So, I would say, we need to refactor ArrayList into Set, but then there 
will be more potential regression impact. I'd recommend to keep it as is for 
this PR/Jira, and have another ticket opened on cosmetic improvement to change 
ArrayList to to some Set implementation during initialization. I hope it makes 
sense.

Ok, that makes sense.  Thanks for the explanation.

@ottobackwards , when a processor is invalid (customValidate returned 
validation errors), we keep all the validationResults. Method 'customValidate' 
just check if there are already errors - no need to validate again, just return 
whatever is stored.
When any property is getting modified - these validation results may not be 
accurate anymore, so we have to reset them. Once reset (onPropertyModified), 
next call to customValidate will run full validation and set new errors if 
found. So at any point we don't drop validation results for no reason. Am I 
missing anything?

Also, I don't understand customValidate.   The validationResults are used 
to 'seed' the currentValidationResults, but if empty, any new validation 
results are not set back to validationResults.  Is that right?

Why are we using HashSet here, when we initialize to ArrayList initially?  
Shouldn't they be the same and consistent?
