> Recently after upgrading from 2.10.3 to 2.11.0 I have encountered the

> The problematic part was looking like this:

> from("direct:start")
>     .setHeader(Exchange.FILE_NAME, 
> simple("{{file.rootdir}}/${in.header.CamelFileName}"))
>     .to("mock:result");
> {code} 
> Camel was failing to start with the following exception
> {code}

> I have created a small test to reproduce the bug, and thanks to git bisect I 
> found the commit that introduced this bug. It is commit ea4c0ab5 "CAMEL-6233: 
> BridgePropertyPlaceholderConfigurer does not support nested Spring 
> properties". The problem is that it is trying to resolve the whole simple 
> with the property resolver but after resolving the spring property it treats 
> {{$&#123;in.header.CamelFileName&#125;}} as a spring placeholder and fails to 
> find it.
> There is a workaround. If {{&#123;&#123;file.rootdir&#125;&#125;}} is 
> replaced by {{$&#123;properties:file.rootdir&#125;}} then Camel starts just 
> fine.
> The test to reproduce is attached.
