> and you want to use the property concat.property. Using Camel 2.10.3 loading this property
doesn't create any kind of problem. When I upgrade to Camel 2.12.3 I get an exception, that
you can reproduce with the following informations.

I found a strange behaviour relative to that specific kind of property.  When I execute a
test like the following, (the first try to use concatenated property and the second try to
use property without concatenation):

> It seems that *DefaultPropertiesParser* doesn't like concatenation of properties. I've
forked Camel project on GitHub and I've added the unit test posted above. Here is the link:
https://github.com/ancosen/camel
> Investigating the history of the particular class I found that the problem should arise
from:
>  *CAMEL-5328 supports resolution of nested properties in PropertiesComponent*
> Here is the link of the commit:
> https://github.com/apache/camel/commit/83f4b0f485521967d05de4e65025c4558a75ff3c
> Thanks.
> Bye
