Solutions

1. Specify a target type for the dynamic instantiation ('new com.foo.Dto(...)').
2. Check the query syntax of the select clause.

When it happens

Trigger: A dynamic instantiation (select new) target cannot be constructed.

Common situations: Using 'select new SomeClass(...)' where the class is missing or has no matching constructor.
