Trying to run importer-jdbc tests I've found the GrowableInternationaString
coverter being used to convert an exception (ImportTask has a field that's an
exception):
```

```
This happens because the converter has the class check in ``canConvert``
backwards, checks if the target class is a superclass of
GrowableInternationalString, and the ThrowableConverter, for some reason, may
search for a "converter of Object.class".
Does not always happen, seems to be related to a classpath lookup chance.
