Groovy processors

You can use Groovy closures to define the processors in Java DSL. Static method org.apache.camel.groovy.extend.CamelGroovyMethods.toProcessor provides a bridge between Groovy closures and Java:

...
from("direct:start").processor(toProcessor{ Exchange exchange ->
  exchange.in.body = 'body'
