Claus Ibsen resolved CAMEL-5172.
--------------------------------

    Resolution: Fixed

The Type Converter API has been adjust accordingly. Now the default behavior by the Camel type converter system, is to fail fast, and propagate exceptions back the the caller by default. You can use the new tryConvertTo to use the old behavior.

> The org.apache.camel.TypeConverter API would not propagate exceptions that would occur during type conversion back to the caller. But instead return null.
> We should tighten this up and introduce a new API for trying to convert, so what we would have is
> - convertTo = converts, and throws exception if failure during conversion, can return null, if no value to convert, or no type converter exists to do this
> - mandatoryConvertTo = convertTo + will throw exception if no value, eg it never returns null
> - *new* tryConvertTo = convertTo but will catch exceptions and return null (like the old behavior)
> This introduces an API change in TypeConverter. But it is more intuitive. There is some internal logic that needs to be adjust a bit due they rely on the old behavior.
