Description

Setting properties like:

camel.component.netty-http.configuration.maximum-pool-size=20

... to configure the netty-http-starter component produce class-cast errors.

Caused by: java.lang.ClassCastException: org.apache.camel.component.netty.NettyConfiguration cannot be cast to org.apache.camel.component.netty.http.NettyHttpConfiguration

The reason is that the netty-http Component, that inherits from the netty component, requires a subclass of NettyConfiguration (NettyHttpConfiguration), while the generated starter is using the parent class.
