---------------------------------------

             Summary: CamelContext fails to start using placeholder in "simple" 
in conjunction with BridgePropertyPlaceholder
                 Key: CAMEL-6400
                 URL: https://issues.apache.org/jira/browse/CAMEL-6400
             Project: Camel
          Issue Type: Bug
          Components: camel-spring
    Affects Versions: 2.11.0
            Reporter: Nerses Aznauryan


Recently after upgrading from 2.10.3 to 2.11.0 I have encountered the following 
bug.
The problematic part was looking like this: 
{code}
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}
org.apache.camel.FailedToCreateRouteException: Failed to create route route1

{{file.rootdir}}/${in.header.CamelFileName}}] <<< in route:

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.
