Set TTL Apache Camel JAva DSL

Question

How do you set the TTL for a message when using Java DSL?

I have something like this:

...
from (\"timer:something?delay=3000&period=15000\")
   ...

I ended up setting the JMSExpiration header field of the messages being created similar to the following

.setHeader("JMSExpiration", constant(System.currentTimeMillis() + 1000))

We are using Apache ActiveMQ 5.7.
