Description
It should be possible to provide a custom TypeConverter for converting strings into an Enum instances.
The conversion of `String` to `Enum` is hard coded to fail with an Exception if `EnumTypeConverter` cannot instantiate an `Enum` constant by name. However, Java allows to override the string representation for enums. Converting such strings back to enums is only possible through a special converting function.
Currently `org.apache.camel.impl.converter.EnumTypeConverter` tries to find the Enum instance by name. If that fails it falls backĀ to calling the built-in valueOf(String) method which will end the program with a RuntimeException. The type conversion process stops there instead of further looking for custom type converters. The line with `return null;` in `EnumTypeConverter` is never reached. Would `EnumTypeConverter` indeed return null, the process would continue and a custom converter would finally be called.
