In the JMX section of the Apache Camel docs, a new section has revealed an upcoming feature for Camel 2.12.
Camel enlists MBeans, such as endpoints configured with URIs, in JMX by default. Camel 2.12 is going to provide a way to hide the sensitive information, such as passwords, that is contained in these configurations, using a simple "XXXXX" as the replacement value. URI masking, essentially.
Check out the Spring and Java DSL examples in the docs. There's no set release date for Camel 2.12 yet.
