 You can provide a custom conversion handler class by use of the 
`runtime.conversion.handler` property. The class must implement the 
[`org.apache.Velocity.util.introspection.ConversionHandler`](apidocs/org/apache/velocity/util/introspection/ConversionHandler.html)
 interface. Set it to `none` to only accept default Java conversions, as for 
Velocity 1.x.
 
 You can also provide custom 
[`Converter<T>`](apidocs/org/apache/velocity/util/introspection/Converter.html) 
objects that handle a conversion towards a specific type:

 You can provide a custom conversion handler class by use of the 
`runtime.conversion.handler` property. The class must implement the 
[`org.apache.Velocity.util.introspection.ConversionHandler`](apidocs/org/apache/velocity/util/introspection/ConversionHandler.html)
 interface. Set it to `none` to only accept default Java conversions, as for 
Velocity 1.x.
 
 You can also provide custom 
[`Converter<T>`](apidocs/org/apache/velocity/util/introspection/Converter.html) 
objects that handle a conversion towards a specific type:
