In class GetInstancesFromServiceLoader, thrown ServiceConfigurationErrors are not logged:
{{
try {
instances.add( iterator.next() );
}
catch (ServiceConfigurationError e) {
// ignore, because it can happen when multiple
// services are present and some of them are not class loader
// compatible with our API.
}
}}
There are cases where it would be useful if these were logged after all.
Take for example the case where a developer adding a new ConstraintValidator has made a mistake and has not provided a no-args constructor for the validator. ServiceLoader will in this case fail to load the ConstraintValidator, but this will not be obvious to the developer. |
