??? UnsupportedTypeException or should it be

Or just AmbiguousConstraintException?
Constraint implementation

not wrap
UnsupportedTypeException
isValid incompatible type (detected by impl) => same as
"declared property type property has no match"
ConstraintExcecutionException
isValid throws a RTE will be wrapped into
ConstraintValidatorExecutionException
ConstraintCreationException
ConstraintValidatorFactory fails with RTE. Wraps it.
??? should we collapse that into a ConstraintExecutionException or even
ValidationException
I could imagine to just use ValidationException in the case of
ConstraintInitializationException, ConstraintExcecutionException,
ConstraintCreationException
I don't know which different type of action a developer should take in the
case these exception exist. And is ConstraintExcecutionException not really
just another name for ValidationException?
3. Bootstrap
ConfigurationException
cannot read XML cong
more than one XML conf
no no-arg constructor on classes described by XML
MappingException
cannot read XML mapping
entity described more than once
field/getter described more than once
Wrong class / field / getter name
Wrong constraint declaration
Wrong constraint definition
What's about combining ConfigurationException and MappingException into
just ConfigurationException?
B. EXCEPTION MODEL
We have three approaches:
1. specialize an exception when the application can do something about it
In this case all exceptions are ValidationException except
ConstraintViolationException
+1 for this approach.
