OK, I found the issue, it's related to property placeholder: https://issues.apache.org/jira/browse/CAMEL-12570
So, it affects users when using property placeholder in the camel blueprint route. To work, users have to use at least Camel 2.21.2. If an user still uses Camel 2.20.1, it won't work. That's why I think it's better to: 1. stay with blueprint-core 1.9.x on Karaf 4.2.x 2. do a a new blueprint-core 1.9.1 release including the interceptor fix we need for jpa Thoughts ?
