Description

Assuming we have a simple route like:

from("undertow:http://localhost:{{port}}/incompatibleData")
    .transform().constant(Collections.singletonMap("key", "val"));

This code will cause an NPE on UndertowConsumer because the body cannot be converted to a ByteBuffer [1], instead of an NPE we should use mandatoryConvertTo so the exception is more clear.
