Review comment:
Without that change the compiler would complain as:
```
[WARNING]
/Users/bvahdat/dev/workspace/camel/components/camel-jms/src/test/java/org/apache/camel/component/jms/JmsMessageBodySetNullTest.java:[86,42]
non-varargs call of varargs method with inexact argument type for last
parameter;
```
The problem is that `BuilderSupport#constant` is overloaded (which doesn't
really fits for the `null` case):
```
public ValueBuilder constant(Object value)
public ValueBuilder constant(Object... value)
```
And the compiler thinks we intend to invoke the second one and gives that
warning above. To overcome that I did that change to make it clear and resolve
that warning.
Instead we could also do:
```
.setBody(simple("${null}"))
```
