Predicates with two types should consider casting to desired type before 
evaluating
-----------------------------------------------------------------------------------

                 Key: CAMEL-772
                 URL: https://issues.apache.org/activemq/browse/CAMEL-772
             Project: Apache Camel
          Issue Type: Improvement
          Components: camel-core
    Affects Versions: 1.4.0
            Reporter: Claus Ibsen


I had this unit test where I want to assert that the message body contains this 
string part
{code}
        MockEndpoint error = getMockEndpoint("mock:errorQueue");
        error.expectedMessageCount(1);
        error.message(0).body().contains("<patientCpr>0101701234</patientCpr>");
{code}

But the expression fails because the body is byte array and is not casted to 
String as the contains type is.
If I change the code to:
{code}
        
error.message(0).body().convertTo(String.class).contains("<patientCpr>0101701234</patientCpr>");
{code}

Then it of course works. But what if there already is a type convert in Camel 
that could have done the cast for me?

But is it dangerous to add such automatic type casting behind the end-users 
back? Any thoughts?
